Fenrir

A divine spellcaster and chosen servant of the imprisoned Gnoll Demon Lord, Fenrir and his horde scour the lands in search of their master's prison to see to his release.

In vain hopes to bolster the numbers to their cause, Fenrir used an artifact to open a portal into the Abyss, releasing hundreds of demons over the course of a week until the Adventurer's Guild of Eskarya sought to close it, slaying Fenrir to return the fiendish Gnoll back to the Abyss, closing the portal and securing the relic.
