The Serpent of Hillcamp Woods
2 pages; PDF.
A victim of the archdruid Tarnagost, Syahasi is a giant constrictor snake awakened a decade ago and left to wander in a world that suddenly made horrible new sense. Since then, she has settled in Hillcamp Woods, becoming a boogeyman figure to the nearby villages. She learned to focus her senses in her woodland home and developed skills for hunting very dangerous game indeed. For years, she preyed on travelers passing through her forest, so locals learned to stay out of the woods. Now, she must go further afield in search of prey.
An intelligent animal antagonist/monster for your 5e fantasy campaign.
