Shyrack

Eyeless, winged monstrosities that hunt in swarms, shyracks are cave-dwelling terrors indigenous to Korriban. Fiercely territorial, they attack intruders with aggression and frenzy.

Typically cave-bound, every sixty-three years the shyracks of Korriban spill from their habitats every day for the entire summer. They fill the sky, blotting out the sun and moon, and rain their bluish droppings onto everything below. Before the Sith returned to reclaim Korriban, every sixty-third summer saw biologists from across the galaxy descend on the planet to observe the purpling of the red terrain.
