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
Spawn of Shub-Niggurath (AC 12, MV 240 [land] / 150 [fly], HD 5, Chaotic): a Jale plant with a smooth hide, 3 eyes, and a beaked mouth. The creature is extremely cold: 1 die damage per round to all within 20' Harmed only by fire.
Village of 348 Dolm Men ruled by a Neutral 4th-level Fighter.
2702
A squat Purple Man Sorcerer (AC 12, MV 90' / 120' \[Flying\], HD 2, Lawful) in flowing robes and an over sized hat is in the process of botching the ritual _The Glyphs of the Ebon Lake_.
4 Black Men camp along a dirt road. They are under the control of a mummy brain, which they are transporting to 2015.
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.
A Purple Man hangs limp from a tree. He is pierced head to toe by spikes. Two tridents lay near his lifeless body.

Village of 221 Brown Men ruled by "the Jewel of the Elements," a Neutral 1st-level Spawn of Shub-Niggurath.
2706
Village of 156 Green Men ruled by "the Dragon," a 4th-level Sorcerer. The Sorcerer's research has left him disfigured: he has the scales and tail of a lizard, and is cold blooded.
Ancient runes are carved into earth, filled with red clay.
2707
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.
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 B'yakhees.

2712
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.
Citadel of 113 Green Men led by "the High Queen," a Neutral 8th-level Sorcerer.
2713

Village of 200 Jale Men ruled by a Neutral 2nd-level Sorcerer.
2715
Castle of 60 Black Men led 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
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.
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.
