Laravon

An icy desert. Sinkholes dot the land. The plants are porous brown trumpets pointing up at the sky.
Massive herds of tentacular, many-colored beasts move across the planet in time with the seasons. They reproduce by splitting along their seams, resulting in several equally-sized offspring.
The tomb of a long since extinct civilization's Emperor is located at the northern ice cap.
Tundra and a few frozen lakes. Towering columns of black stone are viewable from space. There are scattered red fungi.
Every seven years, billions of rugose creatures hatch all at once and begin to swarm, eating everything in their path. They track down their prey using their psionic powers.
There are skeletons here that look almost human, but not quite. Habitability: 20% Size: 6
