A hollow serpent is the dried and shriveled husk of an enormous constrictor snake, animated by fell magic to serve its masters.

Despite their menacing reputation and great power, hollow serpents are a relatively uncomplicated creation. They were designed first and foremost as guardians, and serpentfolk liches of a suitable level of power are sometimes accompanied by hollow serpents. A few have struck out on their own over the years, usually due to outliving their original creators. Driven by their hunger and dim intellect, they take up residence in remote ruins or deep caverns.
