Ysylas

Ysylas was an Ice World located in the Sabbat Worlds in the Segmentum Pacificus.

History
Ysylas served the role of a basic Feral World priorly, being of little importance to the Imperium. The planet was however helped out after a large amount of deaths in the planet's climate. Ysylas was often raided by nearby Orks afterwards, stealing technology and making life harder for the inhabitants every time, returning to sister-planet Isolum afterwards.

Taking note of the attacks, the Imperium tracked down the Orks to Isolum, and immediately dispatched a nearby chapter, the Sons of Redemption. The Sons of Redemption quickly dispatched of the Orks, leaving little of worth, apart from a captured vehicle and a few relics, behind at the planet.

Ysylas later became a recruitment world to the Sons of Redemption, along with Hive World Tefran.
