This is very much a work in progress. (As evidenced by the repeating entries you might see below.) Anyway, here are 16 random hexes.
2701
Village of 62 Purple Men ruled by a Chaotic 5th-level Sorcerer.
A hulking Blue Man (AC 15, MV 120', HD 6, Chaotic) with unusual red hair wields a cursed two handed sword. (This character wields the sword one handed, carrying a shield in the other.) Any character possessing the sword is compelled to eradicate all white men from the world; with each white man they kill their hair turns a darker shade of red. The sword is -1 to hit, but +3 to hit vs. White Men.
2702
A damaged Alien vehicle, with 4 tank treads instead of wheels. Characters with an intelligence of 16 or more may attempt to repair the machine, with a cumulative chance of 10% per week of succeeding. (i.e after ten weeks the tank will be repaired.) It is large enough to comfortably transport 12 men.
Spawn of Shub-Niggurath (AC 12, MV 120, HD 3, Chaotic): a Brown ooze/slime with a scaled hide, multiple/insectile eyes, and a beaked mouth. Immune to cold.
2703
Village of 336 Dolm Men ruled by "the Light of the Eyes," a Lawful 6th-level Fighter.
Spawn of Shub-Niggurath (AC 14, MV None, HD 3, Chaotic): a Purple ooze/slime with a smooth hide, 3 eyes, and multiple mouths.
2704
1 Deep One.
Spawn of Shub-Niggurath (AC 14, MV 120, HD 6, Multiple Alignments \[intelligent\]): An Orange humanoid with a smooth hide and 3 heads. One head is humanoid (and Lawful), one head is robotic (and Neutral) and the last head is bestial (and Chaotic). When first encountered, or whenever the creature is under stress, roll a d6 to see which head is currently in control of the beast: 1-2 - the humanoid; 3-4 - the robot; 5-6 the monster.
2705
4 of the Great Race.
Spawn of Shub-Niggurath (AC 16, MV 210 [land] / 240 [swim], HD 5, Chaotic): a Dolm anthropoid with a smooth hide, 5 eyes, and multiple mouths. Surprised only on a 1. Immune to heat/fire.
2706
5 Mutant Camarasaurus (AC 15, MV 60', HD 12, neutral). Smooth Ulfire hide. Invisible.
A large space alien bomb stands upright in the plains, weathered to the point where it is merely the suggestion of a bomb: 1-6, inert; 7-9, still live, disturb it and it will explode (Save vs. Death if within 30' - save equals 2D10 damage, failure is death); 10, actually a space capsule - contains ancient body in space alien battle armor.
2707
A floating circular platform of Space Alien technology hovers 15' above the ground. 1 in 6 chance to figure out how to operate (intelligence modifier applies, only one attempt per character). Can be moved at a rate of 10' per turn. 3 Bone Men with spears have built a hut on top, and "desert fishing lines" hang from the platform. The Bone Men are extremely xenophobic (reaction roll penalty of 2). One of the Bone Men has 2 sleep gas grenades (as sleep spell but a save versus paralysis applies, 30' blast radius).
Spawn of Shub-Niggurath (AC 17, MV 90, HD 2, Neutral [unintelligent]): a Yellow amoeboid with a scaled hide, 6 eyes, and a suckered mouth. Immune to cold.
2708
Spawn of Shub-Niggurath (AC 17, MV None, HD 4, Chaotic): a Bone octopoid with a suckered hide, 3 eyes, and a suckered mouth.
Spawn of Shub-Niggurath (AC 16, MV None, HD 5, Chaotic): a Dolm amoeboid with a scaled hide, 6 eyes, and no mouth. Immune to normal weapons.
2709
Castle of 20 Black Men led by "the Lustrous Provider," a Chaotic 8th-level Fighter.
Small inexplicable pond, filled with brightly colored fish. The fish are easily caught and if eaten will grant a temporary +4 HP for the day. The pond and fish will be gone upon return, and attempts to preserve the fish will result in unpleasant smelling mess.
2710
Cuddly fluff balls (2-12, 1 HP each, AC 7). Bright red, hovering, bobbing up and down gently. When observed for a turn there is a 3 in 6 chance of seeing the fluff ball lazily open one or both of its eyes. If petted, a fluff ball will orbit the character. Orbiting fluff balls will give characters a Save vs. Wands to avoid a normal missile (something like an arrow or bullet) that would otherwise hit. A success means that the Cuddly Fluff Ball intercepts the missile and is destroyed.
Spawn of Shub-Niggurath (AC 14, MV 90 [swimming only], HD 3, Chaotic): a Ulfire, White and Jale hexapod with a suckered hide, 4 eyes, and a suckered mouth. The creature has a breath weapon.
2711
Citadel of 49 Bone Men led by a Neutral 4th-level Fighter.
Mummy with lower half of body buried (HD 5, AC 5, eyes shoot 2 lasers, Save vs. Death Ray or take 5 dice of damage). It wears an emerald medallion (2000 GP). Quiescent unless the emerald medallion is disturbed. Two dead orange men lay nearby, one with a scorched hole blown in his head, the other with a scorched hole blown in his chest. 1-6 primitively armed Orange Men huddle at a safe distance discussing how to relieve the mummy of the medallion. They are not interested in treasure other than gems and technology, but will serve if offered such incentives.
2712
A White Woman (AC 14, MV 120', HD 4, Lawful) is locked in battle with a Deep One. She fights with a large wooden staff and is searching for her mother.
Castle of 89 Dolm Men led by "the Servant of the Awake," a Chaotic 7th-level Fighter.
2713
A young Purple Man child weeps alone. He has no possessions save his clothes, and is hungry.
What appears to be a simple rock is in fact The Starseed, a source of unlimited power. At any given time there are at least 1-6 high level sorcerers actively searching for the artifact.
2714
A party of 2-8 inter-dimensional travelers search for their lost companion. They are armed with turn of the century firearms: pistols & shotguns. They are cautious around and distrustful of any natives of Carcosa they encounter. They will however aid anyone who agrees to help them find their friend.
2 Unquiet Worms make their home in the shade of a disabled alien tank. Within the tank, two dead aliens lay mummified in their spacesuits. Sufficiently intelligent creatures can restore the tank to working order after 2-6 turns of experimentation.
2715
1 Spawn of Yog-Sothoth.
1 Mummy Brain.
2716
Village of 218 Orange Men ruled by "the Attendant of Many Hues," a Neutral 3rd-level Sorcerer.
Spawn of Shub-Niggurath (AC 18, MV 90' / 120' [swimming], HD 3, Neutral [intelligent]): an orange anthropoid with scaly skin, two yellow eyes, and a toothed mouth. One of its arms is an oversized claw. In its other hand it carries a green mace.
