Satun

Satun was the previous ruler of the Underworld kingdom. He was overthrown by his children, Desher, Desper, and Ouken, before the start of the series.

Appearance
Satun was a massive figure, easily as tall as a giant like Bosse. He had a shaggy mane of gray hair, an enormous shaggy gray beard, thick gray eyebrows, beady black eyes, a pointed nose, and a wide mouth with pointed teeth. His eldest son Desher resembles him.

He wore the crown of the Underworld, a navy blue tunic with purple triangles running down the front, and wielded a gigantic scythe.

Personality
Satun was a God, a species that had largely died out by the end of his rule. He was obsessed with obtaining immortality to preserve his own life, and believed a clue to doing so existed in the human impulse to procreate. He studied this phenomenon by first marrying and siring children with a human woman, Desher, Desper, and Ouken.

Unsatisfied with the results of his humane research, Satun began slaughtering and examining the remains of his own subjects, killing such a great number that his sons & remaining subjects rebelled. Satun was eventually slain by his sons, the oldest of whom inherited his crown as the King of the Underworld.

Godhood
Satun was a God, an unimaginably powerful primordial species that had largely died out by the end of his rule. His abilities far exceeded those of the average human, and he was likely even more powerful than a giant.
