Alden is the father of Fitz, Alvar and Biana Vacker, and the husband of Della Vacker. He is very kind and generous with his hospitality, while also very hesitant with giving information to Sophie and her close friends. His heart is always in the right place and he has always been there to help Sophie become settled into the Lost Cities and find her place, and herself. He has the same crisp British accent as Fitz--it's the same with every Vacker .
