Changes

During the [[Horus Heresy]], the world contained [[Fortress World|fortresses]] and sprawling [[Industrial World|refineries]], that made it a key stronghold and mustering ground, for the [[Iron Warriors]]{{Fn|1c}}. While under the [[Traitor Legion]]'s control, Luth Tyre continuously supplied them with war material, fuel and chemicals. As the Heresy raged in 11.[[M31]], the world's Iron Warriors garrison came into contact with a [[Death Guard]] fleet from [[Barbarus]]. It was among the forces defending their [[Homeworld]], which were in the midst of a [[Subjugation of Tyrinth|campaign]] to seize resource rich [[Imperial]] worlds, in order to form an empire for the Death Guard. After learning of this, the Iron Warriors agreed to give supplies to the Death Guard, in exchange for a share of their plunder taken from pillaged Imperial worlds{{Fn|1a}}. In 12.M31, the Iron Warriors [[Battle Cruiser]] [[Visage of Vengeance]] arrives at Luth Tyre. It had escaped from the [[Battle of Tallarn]], but had been trapped in the [[Warp]] until finally appearing near the Iron Warriors' held world. The survivors aboard the Visage soon join the Traitor Legion's garrison on Luth Tyre and bring with them a large number of indentured [[Mechanicum]] automata. However there is little trust shared between the newcomers and the garrison, who seem to prioritize the needs of the Death Guard over their own brethren.{{Fn|1b}}

Later in that same year, Luth Tyre comes under attack by the [[Passage of the Angels|vengeful]] [[Dark Angels]], who are led by their [[Primarch]] [[Lion El'Jonson]] himself. Because the world sat upon a stable [[Warp Route]], however, the Primarch can not afford to order Luth Tyre's destruction, like he has recently done to other worlds. Instead, El'Jonson demands his [[Orders Militant of the First Legion|Orders]] to capture the world in the name of [[Terra]]. The Dark Angels' fleet then unleashed an orbital bombardment upon Luth Tyre, which set the upper layers of its atmosphere ablaze and fused the world's desert into plains of jagged glass. The Legion's Orders attacked afterwards and though the [[Iron Warriors]] and their [[Death Guard]] allies put up a valiant resistance, they are overwhelmed by the invaders' sheer numbers. One by one Luth Tyre's fortresses and refineries are destroyed by the Dark Angels' Orders, though, they suffer heavy losses as well. As the world begins to fall, a group of Death Guard, Iron Warriors and [[Dark Mechanicum|Traitor Mechanicum]] forces launched a daring attempt to escape aboard [[Warp]]-capable craft. They successfully do so, after fighting through the Orders and packs of raging [[Ambull]]s, to reach Luth Tyre's south pole spaceport. Their crafts manage to evade the Dark Angels' fleet and the world is claimed by the Dark Angels shortly afterwards{{Fn|1c}}. In 13.M41, however, the Traitor forces that escaped Luth Tyre reach the Death Guard's [[Homeworld]], [[Barbarus]]{{Fn|1d}}, and aid in its defense, when the world is later attacked by the Dark Angels.{{Fn|1e}}
