this feels like its gna be good, the duke before supported the 2nd prince and was basically a terrible duke and left all the work to his retainers so when this knight invaded his castle, he ran away and all of his retainers died and he was left starving on the streets. this one armed guy saved him and he believed of him as a saint, aftwards though the duke died and reincarnated into the past where he surrendered to the enemy which saved everyone but basically hes trying to be a better duke and also find the saint again
