This is Irenaeus Precator.
He’s been my fursona for a while, but he’s matured into another character of his own.
He’s... A sort of undead wolf reanimated with cosmic energy, hence why his insides are reference-able as a Starmap.
He’s been around for a while, but still have details to iron out... Like how old he is, or what sort of origins he has prior to his reanimation.

He goes by Iren, but his full name means “Peaceful Protector”.
He resides above a town, riddled with crime and gangs, in a lone cabin beyond sight of said town, where he acts as medical aid for those he finds in need. He once had someone give him the collar and token as a gift, but the words are VERY faded. The tag is, in fact, unreadable.
