Taren

Taren is a centaur woman from The Scarlet Woods and one of the demon prince Gray's moles in the Heroic Oversight Guild, where she works in the archives.

She blames the Thundermen for her fiancé Calhain's death, and reluctantly agrees to help them destroy the Guild at Gray's behest—with the promise that she still plans to kill the boys when they inevitably turn on her.
