The Nord-Breton War was between the High Rock-Skyrim alliance and Cyrodiil. Initially, the war went well for the alliance. However, General Tiber Septim later destroyed the alliance at the Battle of Sancre Tor. The Nords joined Cyrodiil in an alliance, and, in a combined effort, slaughtered the remains of the High Rock forces.
