Hoard of the Dragon Queen
Beaufort FoxTail is an Acolyte clearly working for the Cult of the dragon. He wears dark red robes and is always in the company of a few Kobolds to do his bidding.
It’s clear from his use of magic that he is a wizard of sorts, but the true depth of his power is unknown. It is known however that he can cast the spell Command, which he used on the The Exterminator during the siege of Greenest village.
