Piscciss is a planet made up almost entirely of water. The planet is held together by a gravity amplication device, and for some reason begins to drift apart when such a device is not active or is removed. Previously the gravity application device was a piece of the Map of Infinity, however that was removed so Goop's antigravity disk currently sits in its place.
Piscciss was, at one point, at war with Pyros.
