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 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.
Spawn of Shub-Niggurath (AC 13, MV 90 [swimming only], HD 4, Chaotic): a Blue octopoid with a smooth hide, 4 eyes, and a suckered mouth. Immune to heat/fire.

Castle of 42 Green Men who are currently leaderless.
2703
Village of 130 Dolm Men ruled by "The Master of the Universe," a 1st Level Fighter. He wields a magic sword in battle: on command the sword grants +20 HD, and the saving throws of a 20th level Fighter. Only those chosen by the powers of the Grey Castle may hold aloft the magic sword.
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.

1 Mummy Brain.
2705

Spawn of Shub-Niggurath (AC 12, MV 90, HD 3, Chaotic): a Jale, Purple, Green and Blue arboreoid with a feathered hide, 6 eyes, and a suckered mouth. Immune to normal weapons.
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
18 Diseased Guardians.

2709
A War-Machine, ancient and blasted; once a terror, now a collection of rust.
Castle of 16 Yellow Men led by a Lawful 4th-level Fighter.
2710
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.
A disfigured two-headed mutant man lays face down in the ground. His body is half purple & half blue. Characters who investigate the body must make a Save vs. Death Ray each turn or suffer a random mutation.
2711
Spawn of Shub-Niggurath (AC 13, MV 30, HD 10, Chaotic): a Green plant with a smooth hide, 6 eyes, and a suckered mouth. The creature has 2-9 heads.

2712
A White Woman (AC 14, MV 120', HD 4, Lawful) is locked in battle with a Deep One. She fights with a large wooden staff and is searching for her mother.
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.
2713
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.

3 B'yakhees.
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.
2715
6 Triceratops.
3-18 red orbs can be seen floating in the distance.
2716
Village of 332 Green Men ruled by a Chaotic 7th-level Sorcerer.
