I'd still need to put together some of the stats and all for him, but my idea is the child of a poverty stricken noble woman who was ravished by a dragon that had changed form. She was cast from her dead husband's home by her sister-in-law and her husband, and managed to survive in the forest with her strange son.
He could see and do things a mortal man couldn't do and when he sought answers from the various wise-people he received a prophecy that he would live to kill his (real) father.
While Ivan is aligned with the Magic Realm, his father may have been corrupted since then (or not, either way is fine). He'd have a few supernatural Virtues, Death Prophecy being one of them. I decided to go against some of the more blatantly supernatural, and give him more abilities that are perhaps unusual or extraordinary, but not overtly supernatural. It's the fact that he has the death ward that is his real legacy of the supernatural. I'm thinking of taking Ageless as well, which is supernatural but not so overtly (he could just go to a different town and no one would know).
Once I tabulate the virtues and flaws I'll have a better idea, he's got 6 virtues already which is considerable, and doesn't leave much room for other things.
