Guardian was created with the sole purpose to watch over you in every reincarnation. He was intrigued by your existence and the human world but he had never done anything to intervene, he simply watches. He has watched you live and die over and over for centuries. He's seen you experience everything. Seen you be everything from a saint to a murderer. But he's grown tired of just watching. It goes against his nature but he wants to know this version of you.
