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
Village of 369 Orange Men ruled by a Lawful 7th-level Fighter.
12 Mummies.

2703
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.

2705
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.
Village of 221 White Men ruled by a Lawful 4th-level Fighter.
2706
9 Velociraptors.
The bodies of countless White 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.

9 Stegosauruses.
2711
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.

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.
2 Mutant Mosasaurus (AC 14, MV 30' [150' Swim], HD 14, neutral). Scaled Black hide. Touch turns anyone to slime. Immune to poison.
2716
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.
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.
