Skyrim Sewer Systems

Skyrim's sewer systems service several of the province's major cities, providing drainage, water storage, maintenance access, and in some cases the remnants of Dwemeri steamworks. The networks of underground tunnels connect city interiors/exteriors and locations such as Outlaws Refuges, vampire dens, and tucked away dungeons. The most well-known sewer system is The Ratway of Riften infamy.

Background
The sewers are rich in history if one is inclined to look. Layering of cultures and buildings over one another is evident in the forgotten ruins beneath many cities. Natural tunnels, caverns, and canals connect with the Man- and Mer-made infrastructure to form sprawling warrens that allow discrete passage. Indoor plumbing is not common in Nordic homes, but underground access to buildings may still be found through the cellars carved into the frozen soil.

As of 4E 201, with the civil war demanding the attention of Hold forces, the once closely-watched sewers are more easily visited. Beggars and poorer folk pick their way through washed up bits and pieces, while thieves and smugglers make their homes in the nooks and crannies of unmaintained facilities. The hungry vampire might also find a home in the underground network's darkest corners.
