A river stalker is a type of creature, or perhaps a singular creature, said to exist in the Arteries of the Rainforest within the Laqto. It has untold powers and no form until perceived, at which point it gains a shape and becomes far less dangerous. This shape, however, is not fixed, as these creatures are masterful at disguise, and a person in close proximity to one is likely to never be aware of it. River stalkers are not believed to be inherently malevolent but rather to be instinctual territorial, defending the sections of the rivers in which they dwell against all who pass through.
