Anniversary of William Tell's Shot

710 years ago today: under threat of execution by the Lord of Altdorf, William Tell shoots an apple off he son's head with a crossbow. (A second quarrel was on hand for the Lord if the first didn't work.)

Please Stand By

So us professor-types are hip-deep in a rising tide of work for the academic semester. In my case, I've burned through my backlog of articles to present on the blog and upcoming posts will be irregular at best from now through the holidays (as well as comment replies, emails, these papers on my desk, etc.). I wish I had more time! Hope you have a successful back end to 2017 and hopefully we'll get some interesting stuff coming up soon thereafter.

Mummies Through the Ages

Halloween is this week -- time for a spooky undead-themed reflection. Let's mind-wipe ourselves of the movie that came out this year. Think that energy level drain is horrifying? You ain't read up on old-school mummies lately!

Popular Culture

The golden era for mummy mythology seems to be at the start of the 20th century, coincident with the golden age of Egyptology, especially after the tomb of Tutankhamen was opened in 1922. Within the next two years, a half-dozen members of the archaeology team (out of a group of about 60) had died from various weird causes, and this fueled the popular imagination that there was some "curse" from disturbing the tomb. In particular, Lord Carnavon, the financial backer of the effort, died about 4 months after from a confounding combination of mosquito bite/ shaving accident/ blood poisoning. Others died from fever, malaria, more blood poisoning, assassinations, and being shot by one's angry wife.

Now, apparently real-life curse-inscription texts in Egyptian tombs are pretty rare; but at least one was found that actually reads, "Cursed be those who disturb the rest of a Pharaoh. They that shall break the seal of this tomb shall meet death by a disease that no doctor can diagnose." Read more at the Wikipdia article on Curse of the pharaohs.

A decade later in 1932, Universal Studios made The Mummy starring Boris Karloff (and then a bunch of sequels). Almost 30 years after that, Hammer Film Productions did a revival of The Mummy starring Peter Cushing and Christopher Lee (and then a bunch of sequels). This latter film was often shown in a double-feature with the vampire/Western film Curse of the Undead. In each of these films, the titular character is brought back to life by a magic scroll, and then dark deeds ensue.

Original D&D

MUMMIES: Mummies do not drain life energy as Wights and Wraiths do, but instead their touch causes a rotting disease which makes wounds take ten times the usual time for healing. A Cleric can reduce this to only twice as long with a Cure Disease spell if administered within an hour. Only magic weaponry will hit Mummies, and all hits and bonuses are at one-half value against them. Note, however, that Mummies are vulnerable to fire, including the ordinary kind such as a torch.
In OD&D Vol-2, Monsters & Treasure, Mummies have AC 3, MV 6, and HD 5+1; the above is the entirety of their explanatory text. Even with magic weapons you can only score half-damage on them.

Now, let's look at the rotting disease. It appears that the only effect is to reduce healing rates. But this effect is inescapably permanent. Even if you treat it with a cure disease spell (and it must be within the hour!), your healing rate is still half-normal, apparently forever -- failing that, the healing rate is ten times slower. That makes every combat you ever engage in for the future noticeably more dangerous. Ironically, OD&D doesn't actual set any "normal" rate for healing, so perhaps this really only affects magical curing, which is not called out explicitly; on the other hand, almost all future texts prohibit any magical healing whatsoever to subjects of the disease.

But wait, there's more. In the last few pages of OD&D Supplement II, Blackmoor, Dave Arneson expanded upon the subject of diseases of various types in D&D. And on the subject of mummy disease, the preceding wasn't nearly fearsome enough, and this author felt it needed to be made it much, much worse. He writes:
Advanced Leprosy: The social disease afflicting all mummies, this is what causes wounds to take longer to heal. It is automatically contracted on contact with a mummy. If not cured within three days, there is a 95% chance of fatality, with a 2% decrease each successive day. Any character that succumbs to this dread disease may NOT be raised from the dead; they are permanently dead.

So, apparently on top of the forever-reduced-healing from Vol-2, Arneson gives mummy rot a 95% chance of death per day, and only marginally decreasing over time. The overall chance of surviving such a regime is less than 10−18 (that is: if there was an entire galaxy of Earth populations, and all of them were infected with Advanced Leprosy, then only around 1,000 people would survive to the end). Plus anyone who dies is un-raiseable (perhaps somewhat analogous to those slain by energy draining rising as similar undead).

There's an associated table that says for Advanced Leprosy, "% to Catch: 100%... Fatal %: 60% spec.". that 60% is a bit hard to parse... perhaps there's a 60% chance to die before one even gets to to 3-day mark? And it's also just slightly unclear how the magical curing works in conjunction with the core rule (Vol-1 says "within an hour", Sup-II says "within three days"). In any case, that seems like overkill upon overkill.

Finally: Note that "social disease" is an old-school way of implying "sexually transmitted disease", which I'm not entirely sure what that is meant to imply here in Sup-II. 

1E AD&D

Mummies are undead humans with existence on both the normal and the positive material planes... The scabrous touch of a mummy inflicts a rotting disease on any hit. The disease will be fatal in 1-6  months, and each month it progresses the diseased creature loses 2 points of charisma, permanently. It can be cured only by a magic spell, cure disease. The disease negates all cure wound spells. Infected creatures heal wounds at 10% of the normal rate.
 

The mere sight of a mummy within  6"  will cause such fear and revulsion in any creature, that unless a saving versus magic is successful, the victim will be paralyzed with fright for 1-4 melee rounds. Note that numbers will give courage, and for each creature above 6 to 1 mummy, the creatures add  + 1  to their saving throw...  

Mummies can be harmed only by magical weapons, and even those do only one-half normal damage... Magical fires are at  +1 per die of damage...  Any creature killed by a mummy rots and cannot be raised from death unless a cure disease and raise dead spell are used within 6 turns.

In the 1977 AD&D Monster Manual, Gygax keeps the essence of mummy rot -- one-tenth normal healing; plus the negation of all curative magic (which will be in all editions from now on). And he at least borrows the overall intention of Arneson's supplement; the disease now also deadly, over a period of some months, with Charisma melting off in an apparently leprosy-like fashion. The resistance to even magical weapon blows is retained. He also adds a special fear ability, shown above. Hits have been increased by one die (to 6+3), just like all the undead except for the Ghoul.

But in this case the disease can apparently be entirely removed by application of the clerical cure disease spell -- at any time, in some sense trivial for standard PC parties of a certain level. Unlike Arneson, a raise dead is possible, but with cure disease, it must be applied within 6 turns of death of anyone slain by a mummy (only slightly less harsh). Fire attacks are specified as advantageous (+1 per die).

2E AD&D

The 2E mummy is, for all practical concerns, a copy-paste of the 1E mummy. One thing stands out to me at the end of the combat block: the time frame to cure/raise victims of a mummy has been reduced from 6 turns to 6 rounds.

Also, there is a new separate entry for a certain "Mummy, Greater", which runs about 5 pages in my digital copy. These mummies are ranked by age (less than 100 to more than 500 years), with hit dice from 8 to 13, AC from 2 down to -3, increasing rates of disease progression, and all with spellcasting powers of an evil priest from 16th to 20th level.

This Greater Mummy is perhaps reflective of the overall inflation to monster abilities that occurred in 2E (esp.: dragons and giants), and perhaps borrowing something from Anne Rice's vampire novels which first appeared in 1976 and grew in popularity through the 80's.

3E D&D

Despair (Su): At the mere sight of a mummy, the viewer must succeed at a Will save (DC 15) or be paralyzed with fear for 1d4 rounds. Whether or not the save is successful, that creature cannot be affected again by that mummy’s despair ability for one day.

Mummy Rot (Su): Supernatural disease [slam, Fortitude save (DC 20), incubation period 1 day; damage 1d6 temporary Constitution.] Unlike normal diseases, mummy rot continues until the victim reaches Constitution 0 (and dies) or receives a remove disease spell or similar magic. An afflicted creature that dies shrivels away into sand and dust that blow away into nothing at the first wind unless both a remove disease and raise dead are cast on the remains within 6 rounds...


Resistant to Blows (Ex): Physical attacks deal only half damage to mummies. Apply this effect before damage reduction.


Fire Vulnerability (Ex): A mummy takes double damage from fire attacks unless a save is allowed for half damage. A successful save halves the damage and a failure doubles it.

In many ways 3E D&D "safety bumpered" PCs against the most harmful effects (for example: negative energy drains became temporary with a saving throw). Here, the mummy keeps its fear and resistance to attacks. But by wrapping the mummy rot in the standard 3E disease mechanic, it actually gets somewhat more dangerous; a victim can lose 1d6 Constitution every day, if a daily save is failed -- so likely dying in a few days instead of months as in 1E-2E.

However: The original reduced-healing effect, for both natural and magical means, appears to be removed here (and it might as well be, being effectively negligible compared to the likely death from ability damage in a few days). And fire is made even more advantageous, doing double damage instead of just +1 per die.

The "Greater Mummy" is not included, but a brief line in the stat block indicates "Advancement: 7-12 HD (Medium-size); 13-18 HD (Large)", broadly in line for the extra hit dice allowed in the 2E associated monster.

3.5 D&D

Despair (Su): At the mere sight of a mummy, the viewer must succeed on a DC 16 Will save or be paralyzed with fear for 1d4 rounds. Whether or not the save is successful, that creature cannot be affected again by the same mummy’s despair ability for 24 hours. The save DC is Charisma-based.

Mummy Rot (Su): Supernatural disease—slam, Fortitude DC 16, incubation period 1 minute; damage 1d6 Con and 1d6 Cha. The save DC is Charisma-based.


Unlike normal diseases, mummy rot continues until the victim reaches Constitution 0 (and dies) or is cured as described below.


Mummy rot is a powerful curse, not a natural disease. A character attempting to cast any conjuration (healing) spell on a creature afflicted with mummy rot must succeed on a DC 20 caster level check, or the spell has no effect on the afflicted character.


To eliminate mummy rot, the curse must first be broken with break enchantment or remove curse (requiring a DC 20 caster level check for either spell), after which a caster level check is no longer necessary to cast healing spells on the victim, and the mummy rot can be magically cured as any normal disease.


An afflicted creature who dies of mummy rot shrivels away into sand and dust that blow away into nothing at the first wind.

I'm unaccustomed to the 3.5 edition making things more dangerous than 3E, but it does so here (well, a little bit). First, the mummy hit dice are increased from 6 to 8 (with the possible advanced types running from 9-24). The fear effect is about the same. But the mummy rot doubles up the 1d6 daily Constitution loss with a 1d6 Charisma loss (hearkening back to 1E/2E). Normal healing appears unaffected, but unlike 3E, magical healing (perhaps the type PCs are most interested in) may possibly fail if a caster check does. And the window for raising (6 turns in 1E; 6 rounds in 2E) appears to be entirely eliminated, with a dead victim apparently blowing away as sand instantaneously.

Cure disease no longer has any effect on the victim of mummy rot, as it is now qualified as a curse instead; so something like remove curse is instead required. There is a certain charm to this, inasmuch as the pop-culture conceit is one of the "Pharaoh's curse" (see top), not the "Pharaoh's disease"; although this makes a cure somewhat easier to access, because remove curse is on both the cleric's and wizard's spell lists. Also: the half-damage from blows is gone, although it uses a "damage reduction" ability that shaves 5 points off any attack (so: even nonmagical attacks of sufficient strength can damage it, something not possible in any prior edition).

Holmes D&D

Mummies are also members of the undead. They do not drain life levels, but their touch (if they make a hit) causes the dreaded rotting mummy disease which makes wounds take ten times the usual rate of healing. A cleric can reduce this healing time to only twice normal with a cure disease spell if it is administered within an hour. 

Only magic weapons can hit mummies, and they take only half damage from a hit. Note, however, that mummies are vulnerable to fire, including the ordinary kinds such as a torch, although it only does half-damage to them.

When a mummy is first seen a saving throw vs. a spell must be made or the individual is paralyzed with fear and cannot move until the mummy strikes him or another member of the party. If the party numbers above 5 each member gains a +2 on his saving throw, as their numbers help dispel fear. 

Here's where we check in on the D&D Basic line, starting with Holmes in 1979. The primary project of Holmes was to closely duplicate the rules in OD&D with some of its supplements, with better organizational editing, and only rarely filling in a few gaps with extra rules; and this set the tone for most of the Basic D&D line(s) in the 80's and 90's.

This is almost entirely true for this case of the mummy. Hit dice are the same as in OD&D (5); that is, without the inflation seen in AD&D (and this will remain fixed throughout Basic D&D). The half-damage from hits is the same. The rotting disease is old-school awful as in OD&D; a permanent healing reduction, not fully removable even with cure disease. As in Vol-2, it does not mention magical healing in any way. More importantly, it entirely ignores Arneson's escalation of the disease in Sup-II -- so that while distressing, it is not automatically fatal within a few days of catching it. It does not address or prohibit raising the dead victim in any way (not that raise dead is part of the Holmes level 1-3 basic ruleset).

Now, Zenopus Archives tells us, looking at an early pre-publication manuscript, that "Holmes follows the description in OD&D closely, with no conceptual changes. The two paragraphs in the manuscript are retained in the published rulebook, which adds an entirely new third paragraph describing the fear induced by a mummy."

I think it's been well established at this point that it was Gygax who took Holmes' manuscript and did an editorial pass on it, adding various rules to make it more aligned with his AD&D work. So in this case: The first two paragraphs are really from Holmes, encapsulating the OD&D mummy; and the third paragraph is Gygax, adding in the new fear power from AD&D. Gygax has a bit softer touch here, making the paralysis end as soon as any member of the PC's party is struck by the mummy (instead of a fixed 1-4 rounds).

On the other hand, what Gygax missed in the second paragraph is that Holmes gave mummies only half-damage from fire, whereas in AD&D Gygax gives a bonus to fire damage, so in that respect the two game lines are now running in opposite directions.

Basic D&D

Mummies are undead who lurk near deserted ruins and tombs. On seeing a mummy, each character must save vs. paralysis or be paralyzed with fear until the mummy attacks someone or goes out of sight. In melee, a hit by a mummy does 1-12 points of damage and infects the creature hit with a hideous rotting disease. This disease prevents magical healing and makes all wounds take 10 times as long to heal. The disease lasts until it is magically cured. 

Mummies can only be damaged by spells, fire, or magic weapons, all of which will only do half damage. They are immune to sleep, charm, and hold spells.

The text above is from Cook's Expert D&D (p. X36, 1980). Note that the disease now includes the prohibition on magical healing (not in the prior OD&D or Holmes; first seen in 1E AD&D); however, it is more generous in apparently allowing the magical cure to completely remove the ailment. It retains Holmes' half-damage from fire, in opposition to the AD&D line. Also following Holmes, it is silent on the issue of raising the dead (even that that spell is in this volume). It keeps the paralysis-fear, and ends it if either a PC is attacked, or the mummy moves out of sight; and Cook edits out Gygax's fiddly save modifier depending on number of people in the party.

Mentzer's Red/Blue Box rules (1983) keeps almost the exact same rules text as in Cook. I can see only one change; the sentence about mummy fear does not end the paralysis on a PC being struck -- now, only if the mummy moves out of sight. Allston's Rules Cyclopedia (1991) mummy is word-for-word identical to Mentzer's, except for an added flavor-text paragraph. The half-damage from all blows is retained throughout all Basic editions.

Poll Results

I asked about mummy rot on the Facebook 1st Edition AD&D group. In one of the more lopsided results that I've seen, almost everyone there did seem to prefer the 1E long-acting version of the disease.


Summary



Looking at OD&D, we must admit that there are two separate, really incompatible takes on the mummy's curse of disease. Gygax in Vol-1 plans on the disease being a long-term degradation in recovery ability, over the course of months, perhaps. Arneson in Sup-II expects the disease to very quickly be fatal, within just a few days -- such that the slow-healing effect becomes a forgettable non-issue for practical purposes. Gygax's view held sway in 1E/2E AD&D and the Basic D&D line. But later editions from 3E on recast the disease as did Arneson, fatal in some days if not cured.

Gygax's long-term disease is more in line with the classic pop-culture understanding of the Pharaoh's curse, in which tomb-intruders die horribly months or years later. But Arneson's quick-acting leprosy may possibly be more urgently, dramatically gameable. Which is your preference?

Medieval Demographics in Brief

When I’m developing a wilderness map, I always have to decide, “At what frequency should I place villages, cities, and castles here?” Below you'll find a short document that I've drafted on research for a model on medieval-level demographics. Of course, I'm not the only person to do this, and in fact I don't think this is the only time I've done this; but the document includes copious endnotes so I hopefully stop re-doing this and forgetting which parts are based on real-world data, and which parts I made up for the game.

Here's an executive summary. We use as the basis for our model data from England around the 11th or 12th century;  the population then was around 2 million. (Earlier in the Dark Ages it might have been half or one-quarter this level; later in the High Middle Ages it would be around 5 million, and then collapsing back down to 2 million at the time of the Black Death.) For our baseline in history we find, in round numbers:
  1. Cities: One per 1,000 square miles.
  2. Castles: One per 100 square miles.
  3. Villages: One per 10 square miles. 
(When we say "cities" here we really mean any walled towns.) A variety of examples from Gygaxian rulebooks shows a markedly less dense population, by roughly an order of magnitude (about 10 times fewer features per equivalent land surface area). For game campaign maps, this author is currently using a value about halfway between the two, that is, about one-quarter the baseline medieval population density (i.e., Dark Ages levels). More precisely, we assume that only about one-quarter of the land area is inhabited by humans, with density in those areas approximately the same as medieval England (the rest of the map is left over under the control of various nonhuman races and monsters; in particular, almost any non-plains locations). Therefore this author currently uses, for fantasy realms:
  1. Cities: One per 4,000 square miles.
  2. Castles: One per 400 square miles.
  3. Villages: One per 40 square miles.
This can easily be converted to a recommendation or average on a game map per-hex basis with a little math. Note that the area of a hexagon is \(S^2 \cdot \sqrt{3}/2 \approx S^2 \cdot 0.866\), where \(S\) is the length of the hex measured across opposite edges. (For example, a 24-mile hex is close to 500 square miles; a 6-mile hex is about 30 square miles.) We currently use something like the following map scales:
  1. 100-mile hexes: Shows capital Cities (1 per 30 hexes).
  2. 24-mile hexes: Shows walled Towns (1 per 8 hexes)
  3. 6-mile hexes: Shows baronial Castles (1 per 12 hexes)
  4. 1½-mile hexes: Shows individual Villages (close to castles)
We can otherwise express this by stating that, on average, at Level 1 there is one walled town per hex; at Level 2 one castle per hex; and at Level 3 one or more villages per hex, and therefore these features are not shown on the maps at those scales. The 6-mile hex scale is expected for use in standard wilderness adventure and exploration (smaller sizes permit the entire map to be crossed in a single day, and are generally only used for introductory level adventures, or for added flavor, not strategic movement). We emphasize that at this exploratory level, it makes no sense to depict individual villages (historically, there would be multiple villages per hex); instead, we place castles as shown and assume that each of the adjacent hexes has between 1 and 3 villages in fief (within range of daily patrols, or for a runner/rider to get help within an hour or so). We further assume that the villages mostly have no amenities of interest to PCs (inns, taverns, general stores, etc.) In general we find this makes for attractive and gameable maps, with plenty of space left over for exploration and monster lairs.

Finally, populations for each of the urban features can be simply approximated by the following (this generally hews pretty closely to both historical data and classic D&D rules):
  1. Cities: 10,000-60,000 people.
  2. Towns: 1,000-6,000 people.
  3. Villages: 100-600 people.
A further research question might be this: Is the population scarcity shown in the writings of Gygax consistent with other works of fantasy literature? While likely harder to quantify, this author would hypothesize so. (Consider: Featuring only a single central city in an area that would historically have several, needing to focus the narrative on a few key features, etc.)

Rappan Athuk DM's Log Index Cards

Here's 3 full days of play in Rappan Athuk from this past July, as logged on index-card records during play:
