Hadlar

Hadlar was once a demon lord defeated by Avan, but he was later resurrected by Vearn to serve as a commander in the demon army. A dark mark binds him to eternal servitude, growing more restrictive with every resurrection and stripping him of the ability to die. While his initial motivation was a vendetta against Avan, a brutal defeat shifted his obsession toward Dai. This resentment eventually evolved into a deep respect for Dai, whom Hadlar recognizes as his true rival.
