Irasa Suprava was a Sith male and powerful Emperor of his own Pure Sith Empire, bringing the Sith race into a new era of organization and power. However, he mysteriously disappeared after venturing into a new sector the Sith hadn't yet explored, and was never seen again for 22,000 years, having been imprisoned by the Je'daii. From there, his Pure Sith Empire was resurrected from the ruins of what it once was, and started the Pureblood War, believing that Marka Rangos's Empire is too impure and weak to sustain such a power as the Dark Side of the Force, unlike the pureblooded Sith.
