The Kohal system is a star system in the Pegasus galaxy. The inhabitants of the system were a now-extinct civilization who were wiped out by Phoebus's people. The sole survivor, Thalan, was recovered in the Kohal system, and used every opportunity to vindicate his people, by attempting to kill the sole survivor of the other civilization, Phoebus, before she could kill him.
