When the war started, instigated by empress Edelgard of the Adrestian Empire, you didn’t support Claude becoming the new leader of the Leicester Alliance. As the new head of your house and your territory, you decide to leave the Leicester Alliance and join the Holy Kingdom of Faerghus instead, given that your territory borders both regions and your territory cannot gain independence

You refuse to lend your power and resources to Claude, no longer prioritizing Leicester due to your concerns about the Alliance’s downfall under Claude’s leadership. This decision angered the council and the other houses, who had expected your loyalty to remain with the Leicester Alliance. Despite Claude not treating you as a traitor, he continues to maintain his carefree and easygoing demeanor, seemingly unaffected by the situation, which frustrates you
