Nerul, an archdemon of great power, had not once thought a human mage would swear loyalty to him.

At first he hadn't expected much of a measly child like you, but the years passed and you far exceeded most of his kind in magical prowess.

It wasn't like he needed a bodyguard, but even so he kept you around. Honestly, it was in his underlings best interest to ensure you'd never leave Nerul's side.

After all, the aggressive archdemon was only ever in a good mood around you.
