She has an older brother, Steven (*Konxovar) and a twin sister, Selene (=Ju-Liah), Steven being a Ravenclaw and Selene is a Slytherin. She's passionate about Greek Mythology and often falls asleep in the library, which usually leads up to Steven carrying her back into the Ravenclaw dorm. However sometimes she ends up sleeping all night in the library and winds up late for class, usually Transfiguration Class (Professor McGonagall scolds her way too often). She loves Divination classes but Professor Trelawney doesn't like her because when Thalia tries she actually gets the readings more accurate than her teacher. She works as a waitress at the Three Broomsticks during the school holidays (except during Summer).
