Sewerms were a species of water snake.[1]

Description[edit | edit source]

Sewerms were large snakes with long fangs. Their scales were ideal for blending in to the murky waters of marshes, swamps and sewers. They naturally produced an anaesthetic oil that coated their scales.[1]

Combat[edit | edit source]

Sewerms attacked only warm-blooded creatures. They attacked any appendage of its prey that was underwater, wrapping around it and using their long fangs as an anchor. Their fangs injected an anaesthetic into the bloodstream of its prey. This anaesthetic secretion was so strong that more often than not, a sewerms prey was unaware it was bit.[1]


Ecology[edit | edit source]

A sewerms diet was exclusively the blood of warm-blooded creatures.[1] Sewerms shed their skin only once per year.[2]

Habitats[edit | edit source]

In the Sword Coast, they inhabited many of the marches and swamps along it,[1] including the Mere of Dead Men.[3] They were notorious in Waterdeep, where they were found in great numbers in the sewers. The Cellarers' & Plumbers' Guild considered them a nuisance and working hazard.[1]

Usages[edit | edit source]

The anaesthetic secretion was highly sought after by the Guild of Apothecaries and Physicians for use in treating pain. The extracted secretion could be stored for up to six months. Their skins sold for 2 sp in the markets of Waterdeep.[1][2]

Rumors & Legends[edit | edit source]

In 1491 DR, rumors circulated in waterdeep that a large, albino sewerm was the haunting the deepest and darkest reaches of the city's sewers.[4]
