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
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.

She will aid all those who actively seek to defend Carcosa from the forces of Chaos.

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.
