This planet was founded by an exploration fleet from Terra during the Dark Age of Technology. It was named Urokleas and was an excellent hub for the human race due to strong tides of the Warp flowing through the system. Urokleas prospered, for it was rich in minerals, ores and metals and within a few hundred years humans flourished, building great cities and spaceports.
Then the planet was attacked by Orks, who razed all in their way, leaving behind them only their spores. These spores were the beginning of the future history of the planet. Due to the flow of the Warp, space-faring races again inhabited the Zornian System. Urokleas was an Eldar outpost, the home of a cluster of Spinedorians, and a Hrud warren. At times, the dormant Ork spores erupted, and greenskins developed in some secretive corner of the planet.
At the time of the Great Crusade, humanity returned again. Now the planet was conquered by the force of the Dark Angels Space Marine Legion. Mankind mined there, built the hive cities on the planet and the spaceports on its twin moons. Then, in the middle of M32, the greenskin Waaagh! swept the system. It was the largest recorded Ork invasion, with dozens of conflicts raging across all five Segmentae. Soon, the Zornian System and Urokleas were conquered by Orks. The tides changed again, making the Zornian System no longer easily accessible.
For nearly eight thousand years Urokleas, renamed Urk, was a battleground for warring greenskin tribes. There was no one mighty leader to combine the greenskins into the Waaagh! So the Orks fought with each other in endless battles. That was until Ghazghkull Mag Uruk Thraka was born.
It was then that Ghazghkull received the head wound that led to his famous bionik implant being made and put in by Mad Dok Grotsnik. After this, he worked his way up the ranks, quickly coming to rule over all the Orks of the Goff tribe. There were five tribes on the planet: the Goffs, Bad Moons, Evil Sunz, Snakebites and Blood Axe clans. When the star around which Urk orbited began to die, a Space Hulk appeared and Ghazghkull convinced the Orks to leave on the hulk. It is assumed that since then the planet has become uninhabitable to all life.[Needs Citation]
