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

Burnt out husk of a large Blue tyrannosaurus rex.
Citadel of 46 Bone Men led by a Neutral 10th-level Fighter.
Spawn of Shub-Niggurath (AC 13, MV 120, HD 8, Chaotic): a Yellow arachnoid with a suckered hide, 5 eyes, and a toothed mouth.
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.
A humanoid robot (AC 16, MV 90', HD 4, Chaotic) guards the remains of a crashed alien spaceship. He is armed with a sword and a laser pistol. His 3 large eyes rotate about his head. He can not be surprised and will react with hostility to all who approach.
Ancient runes are carved into earth, filled with red clay.

A party of 2-8 inter-dimensional travelers search for their lost companion. They are armed with turn of the century firearms: pistols & shotguns. 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.

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.
A Jale Man Sorcerer (AC 16, MV 120', HD 8, Neutral) wearing a Red breast plate sits on a giant Cthulhu shaped throne, alone at the lowest levels of the Cavern of the Time Lords. He may share his knowledge of Carcosa with those who seek him out.
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.
Spawn of Shub-Niggurath (AC 18, MV 120, HD 3, Chaotic): a blue arachnoid with two red eyes and a toothed mouth. It currently entangled in a grappling hook and 100' of rope. An orange laser pistol can be found in its belly.
In the centre of a large expanse of rock howling winds bellow out from an open trap door.

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.
