Sibelius Crow was a 19th century doctor. He went to university with George Litefoot. He was removed from the medical register for his extreme experiments on cadavers.
With help from Gabriel Sanders, Crow built a lab under a church graveyard, planning to use the corpses to create an undead army that could conquer the world for Great Britain. He was attacked by Ellie Higson when her vampirism became active. The laboratory was destroyed, burying Crow and his animated army. (AUDIO: The Necropolis Express)
