Past: He formerly served Guest's much older half-brother, Phil. Phil was a bottomlessly kind but stubborn man. He had a bad habit of believing only what he wanted to believe and died after being betrayed by someone he trusted. Cesca warned him many times and urged him to change his mind, but Phil wouldn't listen. Consequently, Phil removed Cesca from his guard duty and ended up dead. Cesca regrets this deeply.
Cesca reached out his hand as soon as he found Guest.
