few things about nasu vers merlin

1. he was born to a succubus

2 he has true magic but its not one of the 5 so how it functions can be weird (since its not one of the 5 it can be replucated by magecraft so its not an inherintly special abilty that causes strategic problems for the enemy it's just really strong {say if the magic was fireballs they would be 100s of times stronger then the second strongest fireball caster})

3 he's still allive so he can't be a servant, yet. also I doubt he's going to die.
