Shadow Mastiffs (Patreon)

You stand. Dusting your self off... as you turn, you realize you're not in the material plane. You are somewhere far worse. In polar opposite to the lush green of the fay wilds before you is spread out a desolate wasteland. 

Before you can even compose your self, a pack of shadows comes charging towards your party. Fighting frantically, these creatures jump from shadow to shadow, biting and howling as more of their kin join the fight.
