The Gate of Divinity

From the introduction: You’ve been quite busy here, deciding allegiances and collecting plunder of great value. Weapons once thought lost to time, and wondrous technology that outstrips anything the Imperium or Chaos has to offer. The alliance of ancient Astartes, and vessels capable of deciding the fate of planets. All of these and more have been brought under your banner, all for a singular purpose. That is, your Ascension.
