A meat-eating hunter, the river serpent, lived in the rain forests of Kirtania, a planet. These serpents, which measured two to three meters long, would lie in wait on the edges of rivers for larger animals to eat, like wild pigs or rodents. The serpents' preferred method of attack was to draw their victims into the river, where they were stronger, and then squeeze and bite them. They were capable of killing prey as large as a Human.
