This Gundarakite death god was both sanctioned and encouraged by Duke Gundar when he ruled the lands that were once Gundarak. He is believed to be a very ancient deity, perhaps a corruption of Irlek-Khan, the demonic entity worshipped by the Neureni hordes who once conquered Barovia eons ago. He is portrayed as a trickster who created death as a deception, and delegated his duties to a host of demons. His neglect of his duties allows the dead to escape, thus creating the undead.
The evil spirits created by Erlik cause misfortune, sickness, and death to mankind. These spirits are imagined as Erlik's assistants. Erlik gives all kinds of sickness and wants sacrifices from the people. If they do not sacrifice to him, he catches the dead bodies of the people that he killed and takes them away to this lower world and then makes them his slaves. So, especially in the Altays, when sickness appears, people become scared of Erlik and make many animal sacrifices to him.
