Wolf Hunt is the fourteenth audio drama for the Horus Heresy Series that was not originally released as part of an anthology or other release. Wolf Hunt was published online in May 2013 by the Black Library as an audio CD. The audio drama was later republished in prose format as an e-book. The title was also published as part of The Silent War main series anthology novel. Wolf Hunt is the direct sequel to Graham McNeill's The Outcast Dead (Book 17) and explains the seemingly erroneous plot hole whereas Magnus the Red's warning to the Emperor came after news of Horus' betrayal at the Isstvaan System.
A fugitive stalks the shadows of the Petitioner's City. Though his fellow Outcast Dead are no more, the lone wolf Severian still intends to escape from Terra by any means possible -- but the enigmatic hunter Yasu Nagasena is in pursuit. As news of the massacre on Isstvan V continues to spread and Severian's trail doubles back to the place where it all began, both he and Nagasena must face some uncomfortable truths, and an even more uncertain future.
