Trystan has light brown hair, blue eyes and light skin.
Trystan is Margaret's son.
Rose is his sister. After their mother's death, Trystan treats her very protective and doesn't want Dom to put her in a dangerous situation.
He comes to accept Dom as his brother and good friend. However, their friendship takes a turn for the worse following Margaret's death, and also (depending on the player's choice) Rose's death.
- After the end of Book 1, Trystan and Rose never appear in the series again. It is unknown why this is.
