Cassandra

Cassandra is an Ehrenfest student, name-sworn to Charlotte.

Cassandra is one of the five student, who's parents are executed for severe crimes committed for either Veronica or Georgine. Thanks to Lady Rozemyne's compassion, she and her fellow orphans are not executed by Aub Ehrenfest, but allowed to live, provided they give their name to a member of the archducal family. Cassandra chooses to give her name to Lady Charlotte and thus becomes her apprentice attendant.
