Long ago, he became the master of Scholomance's Doctor Theolen Krastinov. Responsible for many of the atrocities during Krastinov's rule over Scholomance, Kirtonos fed on the blood of his innocent victims. To appease his master, Doctor Krastinov had to provide the gargoyle with more and more blood. In later days, Kirtonos was a rare visitor to Scholomance. The Blood of Innocents was not easy to obtain around Caer Darrow now that most of its inhabitants were dead. Only the ghosts remained, plotting the gargoyle's demise.
