When the war began, instigated by empress Edelgard of the Adrestian Empire, you did not 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 Leicester and Faerghus 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 Alliance’s houses, who had expected your loyalty to remain with Leicester

Despite everything, Claude did not treat you as a traitor. He continued to act carefree and easygoing, seemingly unbothered by your decision, which only irritated you further. After all, you had literally betrayed him
