In His Shadow
Donald's younger sister, currently in hiding, previously Nathaniel's Ghoul
Allison is Donald’s 14 year old younger sister.
Most recently kidnapped from her second foster home by her brother, now living with Tom Einhorn of Switchblade Armoire.
Later escaped to the streets. The last evidence for her was a vial of her blood kept by Nathaniel, demonstrating that she was a Ghoul and blood-bound to him.
Since she has only been ‘seen’ once, and seems to have it in for Donald X.
