Kerathos is one of 10 Gods in Deathblight.
He is also known as the Hellwolf and/or the God of Death. He created our main heroines as well as the demon kind in general.
As one of the Gods, he got two forms. Most of the time he appears in his human form, but his true form would be a three-headed wolf (similliar to Cerberus from Greek mythology).
He's also the principal of the demon hunter Academy in Belrisca.
His first appearance was in Chapter 2, page 8.
