Era beginning/end
At the height of the Kuretian-Nakaban war, Kureta's eastern enemy was largely defeated. King Alaric knew that one final attack on the capital, Nakaba, would end the war - but at the cost of 1000s of lives. This wasn't what the King wanted. The war had started before his rule, and Alaric had often suspected that the cause was not just. Alaric negotiated a treaty with the enemy force, which would peacefully incorporate their lands into Kureta - but the state of Nakaba would be able to retain some of its independence. In order to appease the generals on Kureta's side, Alaric abdicated the throne to the Orbeck family, who had been the biggest noble family with something to gain in the war - access to the sea ports and its trade routes.
