Gryphonne IV

Gryphonne IV was a Forge World and the home of the Titan Legio Gryphonnicus. Gryphonne IV was one of the few Adeptus Mechanicus Forge Worlds that produced in significant quantities the less common Leman Russ main battle tank variant known as the Conqueror for the Imperial Guard. The plans for this Leman Russ variant were originally discovered on Gryphonne V. Following the loss of the Forge World of Tigrus, Gryphonne IV was (with Stygies VIII) one of two Forge Worlds capable of producing versions of the Leman Russ Vanquisher. Gryphonne IV was attacked and consumed by the Tyranid Hive Fleet Leviathan.
