A planet in Wild Space between Hutt Space and the Rishi Maze. Gamorr, Pzob, and Roon are nearby. Because of an asteroid belt between Kayt and the Corelian Corridor Hyperdrive astrogation directly from core worlds and Kayt is nearly impossible.

In 22 BBY, a dark-force user cult was discovered and disrupted on the planet of Kayt which was drawing force-sensitive miners from the planet’s orbiting space-station High Orbit Mining System. These Force-Users had been worshipping a corpse frozen in Neoniss and called themselves Badthinkers.
