While individual blood eels can deliver a nasty bite, they are rarely a mortal threat (unless its one of those Giant Blood Eels. However, when they swarm they can strip the flesh of a man in seconds and devour schools of fish in minutes. Blood eels are found mainly in the Narrows and Inner Sea, though large swarms have been reported along the coast of Alantaris Isle. Their presence is given away by frothing, bubbling water. Those who have encountered blood eels before, quickly turn and leave the area.
