Any world with more than eighty percent of its
surface covered with liquid water is considered
Class O: Pelagic. These warm, tropical worlds are
able to support vast cetacean populations, as well
as abundant plant and animal life on their sparse
tracts of land. Though humanoids can easily
colonize pelagic worlds, it is rare for civilizations to
naturally arise due to the limited space proffered by
its landmasses.

Due to the warm atmosphere and vast oceans,
violent tropical cyclones are common on pelagic
worlds.
