Nate Crowley is an SFF author and games journalist who lives in Walsall with his wife, daughter, and a cat he insists on calling Turkey Boy.

Steve Lyons' work in the Warhammer 40,000 universe includes the novellas Engines of War and Angron's Monolith, the Imperial Guard novels Death World, Ice Guard and Dead Men Walking, and the audio dramas Waiting Death and The Madness Within. He has also written numerous short stories and is currently working on more tales from the grim darkness of the far future. Thomas Parrott is the kind of person who reads RPG rule books for fun. He fell in love with Warhammer 40,000 when he was fifteen and read the short story 'Apothecary's Honour' in the Dark Imperium anthology, and has never looked back. 'Spiritus In Machina' was his first story for Black Library, and he has since written 'Salvage Rites', 'Fates and Fortunes' and the novella Isha's Lament.
