Sanaa Tryggvassen

Sanaa Wilhelm is a prisoner in Castle Heterodyne. She is the second person to meet Agatha on her entrance to the Castle. She explains to Agatha the motto of the Castle's female population: "Play fair, do your share, and we're there!" warning that causing trouble will lead to death.

She seems relatively kind and level headed for someone sentenced to the Castle, and we don't yet know what she's in for (and whether she is actually guilty of it). She is determined to keep her head down, earn her points, and walk away free.

Moloch von Zinzer has a crush on her, which she does not seem to reciprocate.
