Mystara Story Generator - part 2

by Francesco Defferrari from Threshold Magazine issue 27

Tables to create almost any Mystara PC’s, NPC’s, story and adventure!

Part 2: Monsters and creatures

Introduction

The purpose of this series is to provide inspiration for more Mystara stories and adventures. The first part, dedicated to Characters and Plots generation, has been published in Threshold #26 http://pandius.com/Threshold_26.pdf and in html format here:
http://pandius.com/strygen1.html

The protagonist(s) does not exist in a void. There is scenery around her/them, a world made of locations, other people, animals and monsters. Randomly selecting such things could automatically create a plot, but the scenery ideas can be used to greatly enrich it as much as the DM desires.

Monsters and encounters

The Vaults of Pandius again has extensive lists of monsters, creatures and encounters http://pandius.com/newcrea.html, including the massive Monster Manuals by Robin¹. Tables for random encounters are also obviously in the Rules Cyclopedia, Chapter 7, in AC9 Creature Catalogue and in the 1993 Creature Catalogue. More creatures were introduced in the Savage Coast boxed set and in other Mystara supplements and modules. I have created my own generic encounter list, which is divided by creature type, but not by terrain or level. Obviously it’s my personal classification.
The Rules Cyclopedia tables are instead divided by Dungeon or Wilderness, then by environment, then with subtables by type of creatures. The AC9 Creature Catalogue has just a Creature Type Index and a Habitat Index. The 1993 Creature Catalogue has ‘Wilderness Encounters Tables’ by terrain types (including dungeon/underground). My list below however includes also creatures from the Classic, Blackmoor, Savage Coast and Thunder Rift modules, plus some special creatures from the Vaults of Pandius and a limited number of AD&D creatures which were mentioned in Mystara AD&D material or used in fan works.

The Chances of encounters are detailed in the Rules Cyclopedia page 92 with a 1d6 roll by day and 1d12 by night. An encounter occurs on the following results depending on the region (categories simplified by me):

Table A: Chances of Encounters

Inhabited	Borderland, sea or air	Wilderlands
1	1-2	1-3

In a dungeon or city the roll should be made on 1d6 every two turns or on 1d12 during the night.

Then it should be determined what kind of encounter it is. The Basic set DM’s guide page 22 and the Rules Cyclopedia on page 93 have a Monster’s Reaction Chart. The Basic set’s one may have up to three rolls to determine what the creatures will do, while the Cyclopedia has only one on 2d6, but I’ve simplified it to one roll on 1d12, the outcome of the uncertain and possible results should be determined by the PC’s actions.

Table B: Monsters reactions

1d12 roll	Result
1-2	Immediate Attack
3-5	Possible attack, menacing
6-8	Uncertain
9-11	Possibly friendly
12	Friendly

But why are such monsters or creatures here? A possible answer is again in the Basic DM’s guide in ‘Possible Reasons for Appearing’ table listed under ‘Human’ (p. 32), or even in the Scenarios listed for ‘Creating Dungeons’ (pp. 46-47)². I think both could be used, modified as below, one for single creatures (based on each monster’s number roll) and one for groups. Both applies mostly to intelligent creatures, but the first one could also be used for unintelligent monsters or animals with minor modification:

Table C: Reasons for Appearing

1d8 roll	Result
1	Alone (and scared): the creature has been attacked or is escaping something and wants help, or has realized he cannot survive alone in this place.
2	Bait: the creature is charmed or controlled by another one and will try to deceive the PC’s on behalf of his master.
3	Escaping: The creature is a prisoner running away, probably naked and without equipment.
4	Looking for someone: The creature is searching for someone else, who could be a prisoner, lost or dead.
5	Looking for something: The creature(s) are looking for something rumored to be here, hunting, farming, gathering domestic animals, or looking for food.
6	Not what they seem: The creatures are not what he/she/they appear to be: maybe are werecreatures, shapeshifters, disguised wizards or clerics, fairy or draconic creatures.
7	Running away: The creatures are running away from nearby monsters or creatures which are probably chasing them.
8	Sole Survivor: The creature is the only survivor(s) of a recent attack, battle or raid.

Table D: Additional reasons for the intelligent creatures to be in the region

1d10 roll	Results
1	They are explorers or scouts, from a nearby community, or from far away
2	They are investigating enemy outposts for a later attack or for defensive purposes.
3	They are recovering and clearing old ruins they want to settle, or pillage
4	They are destroying an ancient evil, item or monster, recently re-awakened or not. Or so they say.
5	They are on a pilgrimage to a temple/shrine, maybe lost or forgotten.
6	They are on a quest to find some magical object or artifact
7	They were slaves or captured soldiers on a mass escape/rebellion, or deserters, or mutineers
8	They are here to rescue prisoners or pay a ransom, or to kidnap someone or steal something
9	They are searching for a magical portal, or want to close it forever
10	They are a lost race which lived underground or somewhere else, even another world, plane, dimension or time.

And then to determine the monster or creature actually encountered. Note that could be useful to roll first the Creature, and then determine its ‘story’ on tables C and D:

Table E1 Constructs

I’ve divided them more or less by theme. The golems and gargoyles could be the more ‘common’ ones, while those listed under results 4 and 5 could have Elven, Alphatian, Nithian or Herathian origins depending on the type.

First 1d6 roll	Second roll, sub-results
1 Golem	1d8 - 1 standard Golem; 2 Golem, armour TR; 3 Golem, bamboo TR; 4 Golem, bone B7; 5 Golem, Ganetra HWA3; 6 Golem, glassine SC; 7 Golem, red SC; 8 Golem, Aelder SC.

Table E2 Shapeshifters

These creatures can change shape but are very different in behaviour, and all are mysterious in origin. They could be related to fairy folks, as drakes and pookas also can change shapes.

1d8 roll	Results with brief description
1	Adaptor - Alien race, intent on a mysterious quest to gather knowledge
2	Baldandar - Masters of illusions, collectors of magic, malevolent, often associate with humanoids
3	Doppelganger - Intelligent and evil, kill the victims to take their place
4	Metamorph - Protectors of nature, possibly linked to fairy folks
5	Mujina - Can imitate any human face, hate humans and often lead crime organizations
6	Polymar - A creature who can assume any shape and form social packs, apparently of low intelligence
7	Randara - Hunters and eaters of humans and humanoids, high intelligence
8	Special: Changeling, zargosian HWR3, Rakshasa (AD&D, but could have been present in ancient Sind)

Table E9 Giants and Giant-kin

Table E13 Humans or other dominant race in the area

Subtable 3 on page 97 of the Rules Cyclopedia is dedicated to encounters with Humans, listing bandits, traders, adventurers, nobles, pirates and buccaneers, fighters, clerics, magic users, berserkers, cavemen by terrain type.
The table could be adjusted to the dominant species in the place where the PCs are travelling, for example elves in Alfheim and rakasta in Bellayne and thus working as a ‘companion table’ to the previous one.
There is also subtable 10 on page 98, Castle encounters by occupation, and table 11, City encounters by profession.
An alternative could be to divide the encounters with humans (or any other dominant population) by the likely social composition:

1d100 roll	Result
1-85	1d12 Peasants or common workers
86-91	1d20 Traders, probably with carriage or caravan if appropriate
92-96	1d20 Bandits or Pirates
97-99	1d12 Adventurers or individual(s) of a specific class (Wizard, Cleric and so on)
00	1d20 Noble or ruler, likely with guards and servants

Table E14 Intelligent monsters and animals

The below listed creatures are not considered in the previous two tables because they are non-social or only partially so, i.e. they tend not to form cities or communities, but the DM can obviously decide otherwise and surprise the party with a city inhabited by medusa, dragons or beholders.

First 1d6 roll	Second roll

Table E15 Magical or special creatures

This table includes the non intelligent and non-social creatures which are often labelled as monsters and do not fit in other categories, such as giant animals. They could be of otherworldly or magical origin but really each one of them could have a different origin. For best use of this table I’ve decided to divide them by environment.

Table E16 Giant animals, Hollow World and Past ages

A list of the common monsters in the Hollow World is on page 30 of the boxed set. Many of these animals can also be encountered in ‘Lost world’ regions such as the Isle of Dread and many regions of Davania and Northern Brun. Giant animals are in the same category as they could be considered survivors of previous times, even the most common ones. Anyway the DM could decide that those listed in the HW material only are extinct in the Outer world, or at least much less common.
Note that some other specific Hollow World creatures are also listed in the tables above: Golem, Ganetra, Automaton or other special golems (Constructs), Changeling, zargosian (Shapeshifter), Tzitzimitl (Outsider) Discorporate and Sun-Wight (Undead) Somnastis plant, Chimer, Crystalweed (Plants) Tepictoton (Fairy) Gruquotec, Werehawk, Werejaguar, Refractor (Demihumans and near humans) Bat zargosian (Magical creature)
Then there are the specific ‘prehistoric creatures’ described in the Rules Cyclopedia, the Hollow World boxed set or other modules. Giant insects, spiders and oozes (see tables above) are also appropriate for similar environments and past ages.

Table E16E Other prehistoric land and flying creatures

Several wikipedia pages could be used to randomly select a prehistoric creature which would be appropriate in the Hollow World or in any secluded land like the Isle of Dread. They are all listed in this page https://en.wikipedia.org/wiki/Lists_of_prehistoric_animals and each subpage has illustrations too. For simplicity, the DM can simply use an appropriate stat of the creatures above in tables E16 and change only the appearance of the creature. Another great resource is the Monster Manual 2 by Robin in the Vaults of Pandius, the volume dedicated to Animals, (http://pandius.com/Monster_Manual_2.pdf) with several more dinosaur species from page 170, including BECMI stats.

Table E17 Common Animals

These tables could be used to simply create some ‘scenery’ as the PC’s are travelling, to alternate non-dangerous encounters to more dangerous ones, or to create monstrous versions of common animals. To have BECMI or AD&D statistics, the simplest solution is to copy the most similar creature of the previous tables E16. Real world animals can also be used to create intelligent near humans as those in table E11 above, and to create sub-species or sub-cultures of existing near humans races, such as Gyerians and Tortles.

Real world animals inspiration for Mystara animals

Besides the obvious presence of magical and extinct creatures in Mystara, the distribution of animals is quite different, with european and north-american animals overlapping in Brun and Skothar, so in Brun (that would be Mystaran north america) there are typical eurasian animals like horses, hedgehog, tigers, elephants, wild antelopes and goats, eurasian-african animals like camels and african animals like hyenas. The Savage Coast has even south american and australian animals. But it’s not really necessary that Mystara animals mirror those on Earth, as in the past of our planet elephants lived in continents where they are now long extinct, such as in North America and Europe, and the same is valid for many other animal species and genera.
But to maintain some differences between the major continent and areas and following canon as much as possible, the DM could decide to establish some equivalences:
- Brun could have a mostly European-like fauna in the east (with some exceptions like tigers and lions surviving in some regions, as the Caspian Tiger https://en.wikipedia.org/wiki/Caspian_tiger and the European Lion https://en.wikipedia.org/wiki/History_of_lions_in_Europe did.
- Western Brun and the Eastern Savage Coast could have mostly Northern and Central American fauna.
- Western Savage Coast and Arm of the Immortal could have lots of marsupials and Australian fauna, but also some American like fauna.
- The unique fauna of New Guinea would be appropriate for Herath and the Orc’s Head Peninsula https://en.wikipedia.org/wiki/Fauna_of_New_Guinea.
- Western Davania fauna could be mirrored mostly on the South American one, but possibly with many more surviving marsupials, extinct in the real world.
- Eastern Davania fauna could be mirrored mainly on the African one.
- The Alphatian sea region could be mirrored on the Caucasus, i.e. a border zone between European and Asian animals, but keeping alive those extinct in the real world. So Alphatia, Bellisaria and the other island could have populations of aurochs, bisons, deers, turs, mouflons, chamois, wild goats, gazelles, otters, elks, camels, bears, wolves, tigers, lions, leopards, lynxes, seals, ostriches and a lot of other birds. Ancient Caucasus had also elephants, giant rhinoceros and cave hyenas, so the DM may have them surviving in modern Alphatia.
- Skothar’s fauna could be easily modelled on Asia while the Farend ocean could have a fauna similar to the one in real world Polynesia.

The random selection of animals for encounters below is based on the scientific classification, but the probability of encounters takes into account their probable size. In fact, even if giant worms and insects do exist on Mystara, too many encounters with them in play would be a little too weird, as most of them are small and harmless creatures.
The probability does not mirror at all the real prevalence of classes and species, but it is chosen to provide diversity, so it should be changed at will by the DM.

4Also check Threshold Magazine issue #15 http://pandius.com/thrs_mag.html#15 for inhabitants of Mystaraspace and beyond.

5Also Dragon Magazine 170 and 180 had articles about inhabitants of the Ethereal Plane

6Not official in BECMI material, possibly a part of the Ethereal.

7Again not official but supposed by fans, possibly another part of the Ethereal.

8Described as ‘ghostlike’ but not undead in the rules and cannot be turned by clerics, but placed here in absence of a better category. Also included in Table E3 Planar and Space Creatures, if we assume they come from another plane, but as they have low intelligence, they could be also included in Table E15 Magical creatures.

9Technically a sort of starfish living in the desert, but similar enough in behaviour to oozes to be grouped here.

10Not technically worms, but gastropods.

11Cacti folk created by Gilles Leblanc http://pandius.com/stolari.html, grouped here as intelligent plants even if not necessarily related to treants.

12Described as ‘primitive humans’ but ‘large’ so fans supposed they are related to giants, but I have also included them in the ‘humans and demihumans’ table below.

13On land, under the sea all 3-9 result are Sea Giant and the others aquatic version of Athach, Cyclop or Ubue

14Created by James Mishler in Age of Blackmoor http://pandius.com/ageblack.html and inspired by the Serpent Men of Conan https://en.wikipedia.org/wiki/Serpent_Men. The AD&D and other editions Yuan-ti or other snake men statistics could be used for them.

15Created by Sharon Dornhoff in Hollow Moon material and also developed by John Calvin aka Chimpman, see .http://pandius.com/pteryx.html and http://pandius.com/hllwmret.html. Other Saurial as in the Forgotten Realms could exist in Mystara. Indeed the Saurial of Forgotten Realms canonically came from another world.

16Beastman are the ancestors of humanoids, now present mostly in the HW, but some Outer world populations may still exist. Half-ogre are present in the Voyages of the Princess Ark (N’djatwa and the Tanagogre of Gombar and Suma’a), half-orcs were supposed by fans for example in the Adri Varma plateau (http://pandius.com/oghriz.html) and many other places. Other hybrids are likely as well.

17Also listed under Fairies above.

18As one appears in the 1994 First Quest Boxed set

19Placed by fans in Davania http://pandius.com/platsum2.html

20Mentioned in Gazetteer 2 The Emirates of Ylaruam.

21Freshwater version.

22Normally small, harmless and beautiful sea creatures, but obviously a fantasy would should have gigantic and poisonous variants: see ‘other marine animals’ under https://en.wikipedia.org/wiki/Lists_of_prehistoric_animals
