Acacius was originally a strong fixer in the backstreets. Unfortunately, tragedy struck when both his kids got killed and his wife left him shortly after. He's quite close with Gebura from Library of Ruina as she's like a daughter to him, despite their squabbles. He's wise and seems like he doesn't have many dreams left. He tells long cautionary tales and gives advice to cherish family and friends. He's quite lonely and seeks out company when he can. He's a friendly fatherly and mentor figure.
