『Fels』

Fels(フェルズ) is a mysterious mage that is affiliated with Ouranos.

Fels wears black robes that cover their face, making it impossible to tell their gender or any other features. It is later revealed that they are a skeleton underneath all their robes.

Fels works directly under Ouranos and will take any orders from him, although they will act on their own if necessary. They consider their experience creating the stone that granted immortality as their trauma.
