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
1 Spawn of Yog-Sothoth.
12 Mutant Iguanadon (AC 16, MV 150', HD 10, neutral). Scaled Orange hide. Tentacles for tongues (can grab prey up to 20' away).
2702
17 irrational space aliens herd a group of 15 Green Men into a small metal bunker.
Field of cactus, 2-8 x 100 ft wide/deep. Passing through requires Save vs. Paralysis to avoid 1-4 damage. Cactus are: 1-5 Benign and full of water; 6- Exceptionally refreshing (Heal 1D4 HP when fresh); 7- Hallucinogenic 2-200 Turns of raving madness; 8- Deadly Poison (Save vs. Poison).
2703
Village of 336 Green Men ruled by a Lawful 6th-level Fighter.
Hidden underground lair of 43 Red zealots led by a Lawful 5th-level Sorcerer.
2704
11 Velociraptors.
Village of 333 Green Men ruled by a Lawful 8th-level Fighter.
2705
1 Orange Mastodon. The beast may shoot acid from its trunk 3 times a day.
Spawn of Shub-Niggurath (AC 12, MV 120 [land] / 210 [swim], HD 2, Chaotic): a Dolm and White quadruped with a furred hide, multiple/insectile eyes, and a beaked mouth.
2706
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 Sabertooth Tiger (intelligent).
2707
2 Mutant Triceratops (AC 15, MV 90', HD 20, neutral). Feathered Orange hide. Immune to surprise.
Village of 184 Yellow Men ruled by "the Humble Duke," a Chaotic 9th-level Fighter.
2708
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.
1 Ulfire Jelly.
2709
What appears to be a simple rock is in fact The Starseed, a source of unlimited power. At any given time there are at least 1-6 high level sorcerers actively searching for the artifact.
1 Spawn of Shub-Niggurath (AC 13, MV 90, HD 4, Chaotic): a Red icthyoid with a smooth hide, 4 eyes, and a beaked mouth.
2710
5 Mutant Camarasaurus (AC 15, MV 60', HD 16, neutral). Furred Jale hide. Touch turns anyone to slime.
A Blue Man (AC 16, MV 120', HD 2, Lawful) with a cybernetic augmentation that allows him to extend his head several meters above his body is surveying the wilderness. He is armed with a bright yellow mace and can not be surprised.
2711
A large bird of prey stalks the players. After 1-3 hours it will turn and fly off into the distance. The bird does not attempt to hide its presence.
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.
2712
Village of 181 Red Men ruled by a Neutral 7th-level Fighter.
Spawn of Shub-Niggurath (AC 19, MV 150, HD 1, Chaotic): a Jale icthyoid with a scaled hide, 4 eyes, and a toothed mouth. Immune to heat/fire.
2713
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.
Castle of 68 Purple Men led by a Lawful 7th-level Fighter.
2714
Cuddly fluff balls (2-12, 1 HP each, AC 7). Bright red, hovering, bobbing up and down gently. When observed for a turn there is a 3 in 6 chance of seeing the fluff ball lazily open one or both of its eyes. If petted, a fluff ball will orbit the character. Orbiting fluff balls will give characters a Save vs. Wands to avoid a normal missile (something like an arrow or bullet) that would otherwise hit. A success means that the Cuddly Fluff Ball intercepts the missile and is destroyed.
1 Mummy Brain.
2715
Circle of Standing Stones.
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.
2716
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.
5 Mutant Triceratops (AC 15, MV 90', HD 19, neutral). Suckered Orange hide. Laser Eyes Harmed only by fire.
