When a Tyranid hive-feet descends upon the world of Equestria, Terra sends in the Ordo Xenos, and the Ordo Xenos send in the Imperial Guard. Among the regiments are the legendary Tanith First-and-Only, led by Colonel Commisar Ibram Gaunt. It quickly becomes apparent that theirs is a suicide mission. Can Gaunt fight against crippling morale, Canterlot politics, and the Inquisition itself to save a xeno-world? Will Elim Rawne learn the magic of Friendship? Read on to find out!

Note: Gaunt's Ghosts is the property of Dan Abnett; I have no rights to any of the characters taken from it, and this is a work of parody. For the sake of not spoiling the Gaunt's Ghosts series, all characters are treated as alive at the outset of this fic. Given Abnett's talent for killing off beloved characters, this has forced me to limit how many of the ghosts I include; as such, I apologize if a favorite of yours isn't present.
