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
A massive snake shaped citadel coils around the peaks of a craggy mountain. Within 22 Bone Man are led by a Chaotic 16th-level Sorcerer. He is planning the total conquest of Carcosa.
11 Mutant Lambeosaurus (AC 15, MV 120', HD 9, neutral). Scaled Dolm hide. Covered in spines (when attacked in melee attacker takes a dCarcosa damage and it can throw them like a wyvern). Regenerate 1 HD every 1-3 rounds. Harmed only by fire.
2702
Citadel of 47 Bone Men led by a Chaotic 9th-level Fighter.
2 individuals of Species 23750.
2703
Two Yellow men lay dead on the ground. One is holding a gamma radiation riffle with 10 charges left. There is a 1 in 6 chance the rifle will also irradiate the shooter when discharged.
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).
2704
A large bird of prey stalks the players. After 1-3 hours it will turn and fly off into the distance. The bird does not attempt to hide its presence.
17 irrational space aliens herd a group of 15 Purple Men into a small metal bunker.
2705
Citadel of 61 Blue Men led by "the Brightness of All Truths," a Neutral 7th-level Fighter.
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.
2706
1 Orange Mastodon. The beast may shoot acid from its trunk 3 times a day.
A T-Rex corpse, skin mottled red and orange, is being feasted upon by fist-sized maggots. The top of its skull has been removed with surgical precision, and its brain is missing.
2707
In the centre of a large expanse of rock howling winds bellow out from an open trap door.
Mutant Teratosaurus (AC 16, MV 180', HD 11, neutral). Scaled Red hide. Extremely cold (1 die damage per round to all within 20').
2708
The bodies of countless Bone 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.
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.
2709
Village of 295 White Men ruled by a Neutral 6th-level Sorcerer.
1 Sabertooth Tiger (intelligent).
2710
Citadel of 63 Dolm Men led by a Chaotic 5th-level Sorcerer.
Village of 161 Dolm Men ruled by a Neutral 8th-level Fighter.
2711
5 Triceratops.
A War-Machine, ancient and blasted; once a terror, now a collection of rust.
2712
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.
Spawn of Shub-Niggurath (AC 14, MV 210 [land] / 60 [fly] / 120 [swim], HD 5, Chaotic): a Bone amoeboid with a furred hide, no eyes, and multiple mouths. Surprised only on a 1.
2713
Castle of 20 Black Men led by a Neutral 6th-level Fighter.
3-18 red orbs can be seen floating in the distance.
2714
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.
8 Mutant Trachodon (AC 16, MV 120', HD 13, neutral). Feathered Purple hide. Extremely hot (1 die damage per round to all within 20'). Immune to poison.
2715
12 Black Men led by putrid smelling Sorcerer (AC 18, MV 120', HD 3, Chaotic) are in the middle of casting Manifestation of the Putrescent Stench. The Sorcerer is armed with a laser pistol and wears a bright orange alien space suit.
4 Snake Men attempt to repair a time machine. The Snake Men and their collection of high-tech gadgetry are incomprehensible to characters with an intelligence score less than 18.
2716
Hidden underground lair of 43 Purple zealots led by a Lawful 5th-level Sorcerer.
A Blue Man (AC 16, MV 120', HD 2, Lawful) with a cybernetic augmentation that allows him to extend his head several meters above his body is surveying the wilderness. He is armed with a bright yellow mace and can not be surprised.
