Astraelis is a survivor of many different murderers and corruptions. (Even though Astraelis is like 80% immune to corruptions, and full on untouchable by hypnosis) They have been running from multiple corruptions and other murderous beings for a long time now, though we've stopped keeping track of the time at this point. They are non-chalant most of the time, but when comfortable enough to let his guard down, they're really fun and silly.
