This is very much a work in progress. (As evidenced by the repeating entries you might see below.) Anyway, here are 16 random hexes.

2702
Spawn of Shub-Niggurath (AC 15, MV 120, HD 3, Chaotic): a Purple insectoid with a scaled hide, 2 eyes, and a toothed mouth. Immune to heat/fire.
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.

The sword is -1 to hit, but +3 to hit vs. White Men.

2 Tyrannosaurus Rexes.

A Green Man cyborg (AC 18, MV 60', HD 6, Lawful) leads a battalion of 3-12 soldiers armed with an assortment of Alien weaponry.

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.

Burnt out husk of a large Blue tyrannosaurus rex.
2710

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.
2711
Small inexplicable pond, filled with brightly colored fish. The fish are easily caught and if eaten will grant a temporary +4 HP for the day. The pond and fish will be gone upon return, and attempts to preserve the fish will result in unpleasant smelling mess.
1 Spawn of Yog-Sothoth.
