Originally in service of Redania, Viduka proclaimed his lands as an independent kingdom and gave it the name which elves had used to call it for ages: Caedwen (Elder Speech: White Forest). In order to protect his realm, the monarch formed an alliance with Aedireen, queen in Vengerberg, granting her in exchange the land of Lormark in the perpetual usufruct. The Kaedweni-Aedirnian alliance resulted in the astonishing victory over Redanian army, giving the region of Hagge to Aedirn and territories of Caingorn, Malleore, Barefield and Ban Gleán to Kaedwen. The new border of Kaedwen and Redania proved to be exceptionally durable and became the basis for an equally unchanging peace between both realms. In Hagge, Viduka with great reluctance agreed to keep the promise to his southern ally and hand him control over the Pontar valley. That cession became the beginning of the long-standing conflict between the two eastern kingdoms.
