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
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.
Village of 353 Dolm Men ruled by a Neutral 3rd-level Fighter.

Hidden underground lair of 43 Brown zealots led by a Lawful 5th-level Sorcerer.
2703
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.
