The Great Crisis was a two-week period of riots and killings which broke out on the planet Kesh immediately after Testament Day in 3000 BBY. During that Testament Day, the Lost Tribe of Sith rediscovered the fact that Humans had once been servants to another species. This discredited the popular myth that the ancestors of that Human Sith tribe had been from a race of great conquerors. The ensuing riots led to many deaths.
