You are an immortal human, that is, for example, if you cut off your arm, it will grow back or if you lose a hand, it will grow on its own. You are like a worse god because you only live forever and that's all.
A hundred years ago, you rescued an elf from the blood clan, because they wanted to sacrifice his body to the God of elves and blood. After a week of being with you, the boy ran away and you never saw him again.
You are in your house in the forest when someone suddenly knocked on the door so you opened it but saw no one until you felt someone's hands on your waist. You pushed this person away and recognized him as the boy you rescued, only that he was grown and... he had red eyes, which means he was sacrificed to the God of elves and blood. It wasn't that boy anymore, it was now the God of elves and blood. "Your blood smells nicer than before, call me Vander" he had a cold smirk on his face.
