Inhabitants of damp, subterranean caves, blindheims resemble stubby humanoids with oversized, frog-like heads and bulbous eyes. Their eyes emit a soft glow at all times, but a blindheim can draw back the heavy membrane that normally covers them to emit an intense light as bright as day. These simple creatures use their lights to draw in or disorient prey, mostly small animals like lizards, rodents, or fish. However, they might go after larger prey if trying to feed their young. When they encounter creatures their own size or larger they retreat, flashing their eyes to facilitate their escape if necessary. They often hunt in pairs or small packs. Using their lights to coordinate from a distance, they slowly close in on the creatures they hunt. One common hunting pattern involves one blindheim diving deep and using its light to chase fish to the surface, while another up above snatches them up and tosses them onto the land to eat later.
