Piscines are creatures that share characteristics with fish. Not all Piscines are waterbound, such as the deadly Ichthur, which lives in tropical and arid climes, and hovers about, not unlike an airship, using its fins to guide itself.

Other Piscines include whales, squids, jellyfish, and all manner of strange creatures, such as the great Leviathan, a massive creature resembling both a serpent, and a fish.
