Jago is an ancient, almost lifeless Fortress World located in a group of star systems that form the Sabbat Worlds Sector along the rimward edge of the Imperium of Man's Segmentum Pacificus. The terrain of Jago is mostly flat desert with massive mountain ranges dividing the planet. Partially filled trenches, covered from millennia of sandstorms, cover the landscape. Unknown hands also built barracks, fortifications, pillboxes and trenches which tower far above and below the surface of the planet. The identity of these builders are unknown, as these structures are far to large to have been built by humans or any other known xenos species.
Sabbat Worlds CrusadeEdit
Jago was the site of a covert Imperial insertion to battle the Forces of Chaos, mostly Blood Pact Legions, during the Sabbat Worlds Crusade. Specifically, Colonel-Commissar Ibram Gaunt and his Tanith First-and-Only ("Gaunt's Ghosts") were charged with covering the flank of Lord General Van Voytz's Task Force by capturing and defending the ancient fortress known as the Hinzerhaus, which was built on the side of a mountain, long before the dawn of the human species. During the subsequent battle, nearly half the Tanith regiment were lost, and Colonel-Commissar Gaunt was deemed lost as well.
