Faction Paradox warship
From Tardis Wiki, the free Doctor Who reference
Faction Paradox had several warships during the early period of the War in Heaven. Fitz Kreiner was initiated into the Faction on a warship at Ordifica. Only six warships survived the Time Lords' campaign against the Faction. (PROSE: Interference - Book One) One of the surviving warships was made from a Dæmon skeleton unearthed from Dæmos. (PROSE: Interference - Book Two)
Mother and Father regarded Mathara's fleet of boneships as "skeletons pulled from the influence of the Infernal Sphere". (PROSE: The Story So Far...)
