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
8 Velociraptors.
A foreboding grey castle sits empty save for its custodian, an Orange Woman 18th-level Sorcerer. The castle is circumscribed by a bottomless chasm. A single bridge leads to its imposing doors shaped in the visage of a skull. The sorcerer will not leave the castle, and is immortal and invulnerable while within its walls. She will aid all those who actively seek to defend Carcosa from the forces of Chaos.
2702
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.
2 Unquiet Worms.
2703
Trails of small insects converge on the rocky husk of a massive dead insect. Within an inter-dimensional traveler to Carcosa lays shackled to the ground. Insects crawl in and out of his body. A sorcerer and his minions are in the middle of casting the ritual Canticle of the Crawling God. They will summon the Crawling God in 1-3 hours.
Village of 360 Yellow Men ruled by "the Cunning Thought," a Neutral 3rd-level Fighter.
2704
Village of 253 Red Men ruled by "the Star of Spring," a Chaotic 9th-level Fighter.
3 Mutant Brontosaurus (AC 16, MV 60', HD 29, neutral). Scaled White hide. Breath weapon.
2705
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.
8 Triceratops.
2706
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).
1 Dolm Worm.
2707
A Green Man cyborg (AC 18, MV 60', HD 6, Lawful) leads a battalion of 3-12 soldiers armed with an assortment of Alien weaponry. The cyborg will repair any Alien technology Lawful PCs may possess, and will attack any PCs who make their allegiance to the forces of Chaos known. He is searching for his adopted daughter.
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.
2708
7 Velociraptors.
Spawn of Shub-Niggurath (AC 19, MV None, HD 3, Chaotic): a Black avioid with a scaled hide, multiple/insectile eyes, and a suckered mouth.
2709
An Orange Man (AC 14, MV 160', HD 4, Chaotic) dressed in furs hunts a band of mutant men. He is armed with a whip and accompanied by 2-12 giant beasts and dinosaurs; these creatures are under his complete control.
17 irrational space aliens herd a group of 15 Green Men into a small metal bunker.
2710
Citadel of 98 Red Men led by "The Ram", a Lawful 4th-level Fighter. "The Ram" is a behemoth of a man, never seen without his indestructible helmet.
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.
2711
Village of 279 Orange Men ruled by a Neutral 7th-level Sorcerer.
2 B'yakhees.
2712

3 individuals of Species 23750.
2716
The bodies of countless Yellow Men spill out of a door set into the side of a mountain and completely fill the 10' wide shaft leading into the underground. Obscured by the bodies are ancient Snake Men runes describing 2-8 random sorcerous rituals.
