What is cerbucus?

Cerberus, often referred to as Cerberus in mythology, is a multi-headed dog from ancient Greek mythology that guards the entrance to the Underworld. Typically depicted with three heads, he prevents the dead from leaving and the living from entering without permission. He is often associated with Hades, the god of the Underworld, and represents the boundary between the living and the dead. Cerberus is a symbol of the challenges and fears one might face when confronting death and the afterlife.
