Ripper

Ripper is an ancient who has been cursed into the body of a giant black wolf. He resides in Inferis, where he accompanies Thanatos on work missions when he’s not curled up taking naps.

Hades took him in shortly after he was cursed, and named him Ripper after his habit of growling and snapping at the king when mildly inconvenienced. He took a liking to Arista upon meeting her, and made it his job to protect her whenever possible. He developed a routine of following her to work, and keeping Hades busy when she isn’t around, leaving Hades when he senses she needs him.
