Could be. Hard to say why I'm different. The two theories I got is 'cause my owner is probably a reincarnating hero and so his shadows gets turned into an assassin a lot. Magic sticks around, builds up after enough lives where independent actions turns into independence itself.

Or its 'cause he's a reincarnating hero with a reincarnating princess whose one of the most powerful sources of light in Hyrule and there's something to that whole the brighter the light, the darker the shadow, and that just started doing stuff. Out of most of the hero stories, my owner would be one of the ones closest to the princess. Usually the hero comes from somewhere else, but we grew up with her.
