In DnD, there is a realm called The Beastlands. There, all animals can talk, and live as nature intended them to. Also there, are powerful, demi-god like creatures known as the Beastlords, the pinnacle of their species....
....Shar'roka is one such.
She found the infant Kurg. She sheltered and nursed the infant....and is the reason he can turn into the werewolf form.
