“A monstrous creature ap- proaches the walls!" A guard with a truly terrified look runs toward you, waving his arms with manic energy. "Please! You must help!" Before you can even agree, he grabs you by the wrist and pulls you toward the East Gate. You hear the beast before you see it, bellowing with rage and pounding at the gates. Each time it hits, the entire city shakes. You climb the ramparts and look down at the massive creature with six legs as thick as trees, two spiraling horns, and a spiked tail. This is truly a demon horn the abyss, ' the guard laments. It must be from another plane, so he's not too far off.
