Unidentified flying life form

This huge gray lifeform lived in the atmosphere of a Jovian gas giant.

Biology and appearance
This lifeform lived in the upper clouds of a Jovian gas giant. For its gray color, it stood out from the red clouds of the planet. Along the creature's long underside it had featherly appendages and sphincters which opened and closed repeatedly.

History
At some point in his career, Roark Garnet encountered a member of this species in the atmosphere of the Jovian. The smuggler traveled aboard a bathysphere with some Imperial, when he spotted one of this species ahead of the vehicle. Garnet immediately took control of the vehicle and dove under the lifeform, missing it just with a few centimeters.

Behind the scenes
This species only appeared in an example scenario in the first edition rulebook of West End Games's roleplaying game.
