Ilya Krezkov

The son of the burgomaster and burgomistress of Krezk. He had passed some time ago from a mysterious illness, only to later be ressurected by The Abbot. Though, the spell seemed to take a toll on him, which wouldn't manifest for some time.
A deep hunger began to grip him, causing him to eat more in order to ease the pain. Eventually, his pain would twist his form into a monster which would eat livestock and townsfolk alike. 

When defeated by Gio, his form turned back into that of the small child before his tranformation.
