Yasan Sector

The Yasan Sector is a sector of space in the Imperium of Man located in the Ultima Segmentum near to the Warp rift known as the Maelstrom. It is the sector where the White Scars Chapter homeworld of Chogoris is located.

The Yasan Sector was ravaged by the Traitor forces of Horus and later Drukhari slave raids during the chaos of the Horus Heresy in the early 31st Millennium.

In the midst of the campaigns of the Great Scouring that followed the Heresy, the White Scars returned to their home sector to scour it clean of the remaining Traitors and drive the Drukhari back into the Webway.

The Chapter reclaimed the sector for the Imperium, though during one such battle on the world of Corusil V in 084.M31 the White Scars Primarch Jaghatai Khan disappeared while pursuing Drukhari raiders into a Webway portal.

Following the birth of the Great Rift during the Era Indomitus, the Yasan Sector has come under constant assault from the Heretic Astartes of the piratical Red Corsairs warband.

Their invasion of the sector out of the Maelstorm during the 13th Black Crusade of 999.M41 led to the almost complete loss of the Gartuli and Thaxis Systems to their forces.

While a similar invasion befell Chogoris, the White Scars succeeded in throwing back the Red Corsairs offensive, though at a steep cost.

Heretic forces continue to plague Chogoris and the foundation of Chaos outposts in the sector mean the Red Corsairs will continue to present a major threat to the White Scars' home star system for a long time to come.

Notable Systems

 * Chogoris System - The Chogoris System was liberated from the Red Corsairs' assault, but remnant Heretic forces like mutants and Chaos Cultists remain in place on Chogoris itself, while Heretic raids out of the Maelstrom are a constant thorn in the side of the people of this system's primary world.
 * Gartuli System - The Gartuli System has almost wholly fallen to the Chaos forces of the Red Corsairs and now serves as a base for their continued operations in the sector.
 * Thraxis System - The Thraxas System has almost wholly fallen to the Chaos forces of the Red Corsairs and now serves as a base for their continued operations in the sector.
