Hell Hound Inugami

In times past the infernal forces became aware of the wolf folk as valuable servants due to their loyal nature. Hell Hounds descend from wolf folk that were enlisted into service of infernal lords.

The Hell Hound’s infernal heritage is still present to this day, which comes with unfortunate stigmas. As such many Hell Hounds have adapted a defensive stance in anticipation of hasty judgment of others, or embraced the fear they command. While Hell Hounds still retain the loyalty prominent in their species, they will find themselves often challenging and test the leadership of authority and take command if they deem it lacking.
