3000 years ago
He was the chief sage of Belialuin, and he was who, along the wizard Gowther, taught his daughter Merlin about magic. While Merlin was still a small child her father discovered a way to travel to Purgatory, a dimension that exists between the living world and the afterlife. After a single minute in this dimension Merlin's father returned back looking as an old, invalid person. Bedridden, he explained how Purgatory is a place of chaos where mutilated souls and predatory monsters seek prey, how there's scorching heat, blistering cold and toxic air that destroys the flesh of the living and how time and space are warped, saying that a minute corresponds to a year in there.

Abilities/Equipment
Merlin's father clearly has incredible magical power and knowledge as he was the chief of the capital of the wizards and discovered a way into Purgatory and was capable of surviving in it for a year and returning, although spending so much time greatly weakened him, turning him into an old, invalid person.

He also has the capacity of a "sixth sense" as he stated he relied on it while in Purgatory as perception is lost in there.
