An experimental airship which did not use a elemental as a means of propulsion. Instead, it used a demon. Specifically, the crow-like demon Vritra.
The airship was capable of flight. On its maiden voyage, however, Vritra undid his magic bindings enough to merge with the Exortania, morphing the ship into a horrific monstrosity while the PCs and the crew dived out for safety.
The ship now has crow wings, a stinging tail, and a wide, glass-toothed mouth instead of an observation deck. Reports of the ship are occasionally reported in the Korranberg Chronicle.
