Thalia is selected by Solon and Queen Cassiopea to serve as the Household Steward for Andromeda. She is selected for her years of service as a Household Steward on various estates, and handpicked Iris to serve as Andromeda's handmaiden. She has clear rules set for herself and those she serves, and clear rules about the relations between servants and nobility should be, often advising Androdmeda of the wrong or right thing to do.
