The Steamwraith Emerges.

Destination Zandrelis, Chapter 20.

Zandrelian lore speaks of a massive, ancient entity dwelling in an immense subterranean cavern near the Luminiferous Fields. It is said to be a fusion of organic and mechanical, massive heads of living metal, and a body that exists partially out of sync with normal time. Its eyes are swirling vortexes of temporal energy, and its presence causes physical distortions in the surrounding area. Beware, for it can emerge from beneath without warning.
