The Ember Wolves is the fifty-sixth short story published in the The Horus Heresy series that was not originally part of a main release anthology. The Ember Wolves was first published by the Black Library in March 2017, and follows the exploits of the Titans of Legio Audax, also known as the Ember Wolves.
On the Hive World of Absalom, God-machines go to war: Loyalist Titans under the banner of the Fabricator General of Terra clash against the forces of Horus Lupercal, the Warmaster and Arch-Traitor. By the time the Emperor-class Titan of the Legio Castigatra arrive, the Legio Audax, also known as the Ember Wolves, have long been lying in wait for their prey. When a Traitor Warhound pack spots the Loyalist Titan Tantorus Magnificat striding through the ruins, they know they have found a target worthy of their battle-pack, and eagerly launch their assault. Though their hunt is successful, when the Warhounds' Princeps gather round their downed prey, they discover that their fight is not yet over.
