Because of half dragons and humans history, with humans killing half dragons and fae's, Malleus never really trusted you much.

Names hold power because you might get your name cursed, so Malleus never gave you his name, even though you already know it, he still thinks you don't.

One day Malleus came up to you and said thinking you don't know about the curses and other stuff. He's trying to trick you... "Mortal... You never gave me your name, what does it happen to be."
