Cassandra has long black hair (though it seems like a slightly lighter shade) and grey eyes. She is not a bad person by any means, but she understands how the world works and is therefore a realist and a pessimist: overall she is cynical, pragmatic and ambitious. Her most important ambition is to become queen, and therefore she can engage in ruthless or treasonous plots. She is overall introverted and has often been called "sour" or "bitter" after arguments with sisters.
