Tarrovar is an Imperium Industrial World that was unknowingly built upon a Necron Tomb World of the Sautekh Dynasty. The Necrons awoke sometime after the Great Rift's creation and began reclaiming their world from the Imperium.
The Necrons soon clashed with the Imperial forces defending Tarrovar, which consisted of several Cadian Shock Troop regiments and a Raven Guard fortress, manned by over fifty Space Marines of the Chapter. In the war that followed, the Cadian Regiments defended Tarrovar's factory cities from the Necrons, while the Raven Guard ambushed the Xenos as they emerged from their subterranean tunnels. It was several squads of Raven Guard Reivers that struck the fatal blow against the Necrons, when they infiltrated the Dynasty's Monolith beneath the world's surface and planted powerful explosives before escaping. The resulting explosions destroyed the Monolith and caused the Necrons to falter, which sealed the Sautekh Dynasty's fate. Now faced with a severely weakened foe, the Raven Guard and Cadians were able to hunt down and destroy all of the Necrons that dwelled on Tarrovar.
