Maurice

Maurice is a character from Fire Emblem: Three Houses. He was the original bearer of the Crest of Maurice, which over time would be known as the Crest of The Beast. During a battle in Fódlan's past he became a Demonic Beast while wielding Blutgang and his bloodline and Crest bearers would be seen as cursed. After over 1,000 years, in Imperial Year 1185, Byleth and Marianne finally put him out of his misery when they slay him, restoring his humanity in the process.
