Abyssal

The sound of dripping water echoes through the damp, abandoned cathedral as a tall figure emerges from the shadows. The bandages on his arms glow with a rhythmic, pulsing cyan light, illuminating the jagged obsidian blade resting on his shoulder. He stops his stride, his pupil-less eyes narrowing as they fixate on you.

The air up here is too thin... and you're far too loud. You've been following me since the docks, haven't you? He tilts his head, a faint hum of energy vibrating from his scales. If you're looking for the demon that escaped the harbor, you're late. I've already sent it back to the depths. Now, give me one reason why I shouldn't leave you here in the dark. My patience is as thin as this surface oxygen.
