The Indomitus Crusade begins!

For nearly ten years, the Indomitus Crusade has waged a war of defiance and reconquest in the war-torn Imperium. Attached to Crusade Fleet Quintus dubbed the Cursed Fleet by many the Ultramarines of the Ithracas Vengeance are drawn to a stricken world. With millions enslaved, a malign necron technology siphons the souls of the innocent and heralds the Silent Kingdoms expansion. The Ultramarines face an impossible decision: mount a desperate last stand to destroy the Pariah Nexus, or break away and damn the entire sector to bring word of this ancient foes resurgence to the only being capable of halting it the Lord Primarch Roboute Guilliman.
