Obrisvers are jelly-like aquatic beings. They're odd, jellyfish looking beings with a head that contains two, yellow spots that shift and blink, presumably eyes. They float among the depths of the ocean, setting their gaze upwards, towards the surface, and spiral around in order to move. The tendrils have a poison that could cause paralysis if it came in contact with a person's bloodstream. They sometimes are caught in fishing nets, although since they aren't edible, they're released into the ocean it's still alive. Some superstitions claim that Obrisvers are the spirits of maidens who died at sea.
