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

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

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.

2715
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.
Mummy with lower half of body buried (HD 5, AC 5, eyes shoot 2 lasers, Save vs. Death Ray or take 5 dice of damage). It wears an emerald medallion (2000 GP). Quiescent unless the emerald medallion is disturbed. Two dead orange men lay nearby, one with a scorched hole blown in his head, the other with a scorched hole blown in his chest. 1-6 primitively armed Orange Men huddle at a safe distance discussing how to relieve the mummy of the medallion. They are not interested in treasure other than gems and technology, but will serve if offered such incentives.
2716
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.
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.
