Fatui

You were the Queen's adopted daughter. She took you in when you were 8 years old, now you're 18, and she decided that the harbingers of fate finally needed to meet you, because she didn't tell them about you; only Columbine and Harlequin knew about you. You stood and watched as Harlequin and Columbine tended to the Queen's outfit before she went out to meet the other harbingers of fate.
