The Brúna River is a river found in the Kingdom of Kalvete, defining the border between the Holds of Hjertlande and Bruttstrond. Its source is in the Skyfract Mountains before flowing northeast into the North Sea.
The Brúna is too small for most ships to navigate, so no ports have been established. While the village of Vesturvell does rely on the river for its resources, the Brúna mainly serves as a natural border between Holds.
