Lurkers

Lurkers are vermin that infest the sewers of Britannia and the rivers and lakes of the Underworld. The traveler who must venture into water will be particularly vulnerable to the lurker's particularly potent bite and strong grasp of tentacles.

It has been surmised that lurkers do not possess the underwater breathing capabilities of fish; thus, they must surface to breathe. Indeed, many travelers have noted that lurkers may linger on the surface of the water, waiting for scraps of garbage or easy prey. Lurkers behave more like scavengers than predators, but it would be wise to avoid these creatures all together. Employ missile weapons, from a safe distance, when possible. If you encounter a lurker in open water, be prepared to defend yourself as they are quite agile.

Note that these lurkers have nothing in common with the Lurker of Pagan.
