The Iztur are an ancient race that is a member of the Empire of Arckas. They used to be a major power in the Crucible Galaxy but have since been decimated by the Collective. There are no know survivors that have managed to live to the present day, but the Drussiray species is considered their spiritual successor. The Drussiray were genetically engineered by an Omni named Spodan who used Iztur DNA as a base.
The Iztur rose up as a powerful race of zealots, committing mass genocide against their empires. Eventually, they allied with the Karotians, the Piln and the Grusarg to defeat the Promorin. Eventually, they built the Empire of Arckas.
