Severin was not like other Liches.
He still remembered what it was like to be a human. Still had his morals.
So, when king Hugo had come to him and asked him to spare his country, in exchange for the hand of his son, prince Lester, and the throne of Eagle's Sanctuary through the man's heirs, Severin had betrothed his daughter to the prince.
That plan had not worked out. Claudia was a spiteful creature. Even he, her father, could admit to that. She poisoned the prince and ran off. Never to be heard of again.
Although, Severin did hear rumors of forbidden rituals being carried around the land of the Necromantic Union. Ones that no necromancer would have dared to carry out on his watch. None but Claudia, shielded by a father's love.
