Haun

A haun was a large ice-dwelling worm commanding psionic powers. Notoriously, they were parasites of the giant slugs known as haundar, using them to travel across the ice outside their lairs.

Description
A haun resembled a giant maggot, fat and in length. It had a gray hide covered in fur with black or purple warts scattered across it. The face was small and hairless, instead being covered in a slimy substance, with two tiny black eyes and a mouth filled with serrated teeth.

To move, the haun's internal organs caused constant waves and swells, which were visible beneath the skin. These undulations and jelly-like jiggling propelled it forward at a slow slither. However, once every several minutes, it could compress its body and release it like a spring, leaping up to forward or  upward.

Abilities
Hauns could burrow through ice, which they used to make their tunnel lairs.

Uniquely, hauns possessed innate psionic powers, being capable of making contact and duplicating the effects of animate objects, inertial barrier, and telekinesis of the psychokinesis discipline and aversion (only to worms), inflict pain, invisibility, and repugnance of the telepathy discipline.

Combat
Due to their small size, a haun was unable to bite anything more than higher than it, but once in a battle they could use their springing leap to bite higher up. A favored tactic involved teamwork: one haun would creep behind a foe, and another would force them to fall backwards over it, whereupon both would bite them when they were down.

In any case, they preferred to stay out of melee combat altogether if they could help it. They used their psionics to become invisible, shielded themselves with an inertial barrier, used aversion to worms to discourage foes from attacking them, used inflict pain to harm them, and repugnance to get them to attack each other, while they tried to escape.

Most of all, they'd rather be riding inside their haundars for safety. They commanded these enormous slugs to crawl over and crush their foes.

Society
Hauns had two means of communication. The main one was verbal, and they emitted chattering noises, clicks, faint hums, growls, pops, and snaps according to their mood. However, they could also communicate quietly via their mindlink power.

Lacking arms, hauns were unable to craft tools, goods, weapons, or armor of any form. However, they could use their psionic abilities to manipulate items and objects and even animate objects to do things for them.
