The Battle of Markwasten Moor was the final battle in King Ranser's War, the civil war between the great houses of Rivenspire led by King Ranser of Shornhelm and the First Daggerfall Covenant with the Orcish armies of Orsinium led by High King Emeric and King Kurog gro-Bagrakh. The battle was fought in Markwasten Moor, which is a fortification located in the Westmark Moor region of Rivenspire. After the season long siege on Wayrest, Ranser's army was pushed back into Rivenspire and the houses began to lose hope on Ranser.
Ranser was desperate to win and refused to give up. Emeric's emissaries traveled to the Wrothgarian Mountains to make an agreement between Kurog and the Covenant. If the Orcs helped the Covenant, Emeric would give back Orsinium which was destroyed in the first era. The battle raged on until Ranser's trusted general, General Dathieu murdered him and surrendered the battle. The site originally known as Markwasten Moor was renamed Traitor's Tor for Dathieu's betrayal to King Ranser.
