I think its right to remember that everyone in the arctic is a predator, or a carnivore or more of a vampiric type, hence why they have stocks of blood. Robbie was experimented upon by the sorcerer and Rack found him.

Robbie was turned into a carnivore hence why he has these episodes of hunger where he has no control and cannot remember anything that happened while within that state. Safe to say all carnivores have these hunger episodes which explains the last events of this webtoon. Its also why they said, "All small animals must hide before the winter night." or something among those lines.
