Waterholes are not a welcome sight by any stretch of the imagination. It’s bad enough that the stagnant, smelly flooded streets hinder our progress. But worse yet is that the murky waters conceal whatever might be hiding under the surface.
Stories say trolls like to hide under bridges, but a Swamp Troll hides underwater, always ready to strike at careless survivors who made into these watery traps! Even the bravest knight would wet himself when surprised by this monstrosity (if he weren’t already soaking wet from the waterhole).
