Apostle's Creed is a short story published in the Gaunt's Ghosts series that was originally part of an anthology. Apostle's Creed was published as part of the Sabbat Worlds anthology in October 2010, and was later re-published as a stand-alone e-book.
On the world of Amedeo, Chaos fliers appear as if from nowhere, inflicting grievous casualties and disappearing without a trace. Imperial tacticians are convinced that there is a hidden enemy base in friendly territory, but it remains elusive. Outnumbered, outgunned and outmanoeuvred, the "Apostles", the Sabbat Worlds Crusade's most elite pilots, must find the enemy stronghold and destroy it before the war on Amedeo is lost.
