The Zeplin as imaged by SciFiMix.

Zeplins or zeplens are large floating organisms that inhabit certain gas giant planets. They were present on Whirl, from whence they were extinct. During the Pax Era, they are seen in an alliance with the Akerataeli to assist Ousters and Templars in the construction of the Startree Biosphere.
