Krath

The Krath are a warlike insectoid race native to the Vanaad galaxy. They hail from the planet Cyka, a war-torn and severely damaged planet that they still manage to call home. They are one of the three founding races of the Union, and make up the majority of its military and law enforcement. The Krath are unique among the Union races in that they can "Evolve" into various Forms, specialized for different roles in Krath society.

History
Much of the history of the Krath has been lost due to constant wars wiping out civilization. Their most recent recorded history began about 700 years ago, after a war that decimated their race. The Krath continued to fight amongst themselves, having several more major wars, until 242 years ago, when the nation of Telka conquered their entire planet. Being Krath, however, rebellions soon formed, plunging their world into war once again. Finally, after 40 years of civil war, the rebellions began to die down. The Krath began expanding into space, developing FTL travel and colonizing several star systems. It was mostly peaceful, however the peace would not last. Individual colonies began warring between eachother. The central Krath empire attempted to quell the infighting, resulting in yet another war. This one, however, was over quickly, with most of the Krath remaining unified. The war did cost the Krath several colonies, however, setting back their expansion considerably.
