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
Bipedal humanoid robot (AC 18, MV 120', HD 8) carrying a spear, with a single spotlight eye in the center of a cylindrical head. It is dragging a dead velociraptor behind it. It has learned how to hunt by spying on humans, but doesn't understand what to do with the dead animals: it just drags them back to its cave.
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
Spawn of Shub-Niggurath (AC 14, MV 120' / 160' \[Flying\], HD 6, Neutral \[intelligent\]): A Brown avioid with a feathered hide and a toothed mouth. There is a 4 in 6 chance that when encountered the beast will be in flight.

2703
Ancient runes are carved into earth, filled with red clay.
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.
2704
6 Primordial Ones.
