Knel'char II was a star, one of three around which Darkknell revolved, the others being Knel'char I and III.
During the reign of Sith Lord Daiman on Darkknell, he convinced the people that he constantly observed them via the stars Knel'char II and Knel'char III, calling them his "eyes." Should anyone laugh when the stars' orbits made him appear cross-eyed, Daiman dispatched his Correctors to "correct" the offender.
