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 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 Ooze.
2702
3 Unquiet Worms.
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.
2703
Citadel of 116 Red Men led by a Lawful 4th-level Fighter.
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.
2704
An abandoned space alien outpost is now home to a group of 23 Green bandits. Amongst their possessions is a map of the first level of a space alien research base in hex 0103.
A Jale Man Sorcerer (AC 16, MV 120', HD 8, Neutral) wearing a Red breast plate sits on a giant Cthulhu shaped throne, alone at the lowest levels of the Cavern of the Time Lords. He may share his knowledge of Carcosa with those who seek him out.
2705
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.
Circle of Standing Stones.
2706
Castle of 52 Bone Men led by a Chaotic 4th-level Fighter.
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.
2707
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.
Castle of 3 Bone Men led by a Neutral 4th-level Fighter.
2708
7 Mutant Monoclonius (AC 17, MV 60', HD 12, neutral). Feathered Jale hide. Eyes glow brightly (Gaze causes confusion).
Poison dirigible fruit (2-12, 1 HP each, AC 7). Bright red, hovering, bobbing up and down gently. When touched in any way they explode in a burst of poison glop: all within melee range must make a Save vs. Death Ray or perish. A poison dirigible fruit tree will grow in the corpse of any characters so slain, and will produce 2d6 dirigible fruit in 1d6 days.
2709
A Blue Man Cyborg with a metal jaw and a robotic hook arm (AC 18, MV 90', HD 4, Chaotic) commands a group of 6-36 Blue Men bandits armed with bone weapons. The bandits demand the players hand over any metal items in their possession, which their leader will proceed to eat. The Cyborg earns +1 to hit for each piece of metal he consumes; this effect lasts one day. (When encountered he has a 0-3 bonus to hit.) His hunger for metal can not be satiated.
Spawn of Shub-Niggurath (AC 20, MV 120 [land] / 240 [fly] / 210 [swim], HD 2, Chaotic): a Black amoeboid with a smooth hide, 2 eyes, and a circular gaping maw.

2712
Castle of 25 Brown Men led by a Lawful 3rd-level Fighter.

2713
Spawn of Shub-Niggurath (AC 13, MV 60, HD 10, Chaotic): a Blue ooze/slime with a suckered hide, 6 eyes, and multiple mouths. After a successful attack the creature automatically does 1 die damage per round due to blood drain.

22 Space Aliens.
2715
Village of 241 Yellow Men ruled by a Neutral 9th-level Fighter.
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.
2716
Spawn of Shub-Niggurath (AC 16, MV 240 [land] / 60 [fly], HD 3, Chaotic): a Green amoeboid with a suckered hide, 5 eyes, and no mouth. Immune to surprise. Regenerate 1 HD every 1-3 rounds.
