Karthwasten (also called Karthwasten Hall) was a mining settlement located in the province of Skyrim, within the region known as the Reach. It was notably found near the provincial border near Hammerfell and High Rock. The mixed community of Nords and Reachman were known to mine the veins of silver in the Sanuarach and Fenn's Gulch Mines near the settlement. It was built near the banks of the Karth River, hence the name.
During the Imperial Simulacrum in the late Third Era, the town of Karthwasten Hall was an active settlement, being ruled by Duke Alarke. It had a rivalry with Granitehall. It was neighbored by several settlements, including Amber Guard in the northeast, and Granitehall in the southeast.
By 4E 201, Karthwasten was one of the last pieces of land that was owned by a Reachman, in this case, Ainethach. His family has owned Karthwasten for generations. At this time, Ainethach proved to be unfavorable by both the Nords and the Reachmen, and the hamlet was targeted by the Silver-Blood family of Markarth. Whether the mining town was claimed by the family is unknown, but it remained active nonetheless.
Sometime during the Skyrim Civil War in 4E 201, the town of Karthwasten was the site of a massacre allegedly committed by the Stormcloaks, who disputed their responsibility for the bloodshed. The Imperial Legion would later demand compensation for the massacre from the Stormcloaks as a condition for a temporary truce during negotiations at High Hrothgar.
At around the same time, the Sibyl of Markarth had passed away, and a new one was needed for the House of Dibella in the city. The priesthood had discovered the young girl, Fjotra in Karthwasten, but a group of Reachmen known as the Forsworn had taken her to Broken Tower Redoubt. From there, the young girl was freed by someone sent by the Temple of Dibella, and taken back to Markarth, where she would serve as the Dibellan Sybil of Markarth.
