Cassidy Chacon


 * Cassidy was the past Guardian of Water. She has russet-orange hair, deep blue eyes and freckles and was about 15 years old. Cassidy lived in a house in Heatherfield with her mom Emily, and the two were very close.
 * Cassidy was originally in the Guardian of Water as well as the youngest of the group. When the Heart of Kandrakar corrupted Nerissa, the Oracle decided to entrust it to Cassidy, despite the many risks involved. Angry and envious, Nerissa struck Cassidy down and killed her. Cassidy's death caused a rift between the Guardians as Halinor and Kadma blamed the Oracle for it, stating that he had known what Nerissa would do but gave Cassidy the Heart anyway. The Guardians thus separated.
 * Years later, Halinor wrote in her diary about a Star of Cassidy, that only Will could see. The two were able to communicate spiritually where Cassidy reveals that she does not blame the Oracle for her death, despite what the others feel. She informs Will that the Heart leaves behind a "spark" of itself in each Keeper. Cassidy then gives Will a copy of the Heart of Kandrakar, the Star of Cassidy, which is later reabsorbed into the real Heart.
 * It is also mentioned that Will was born under this star, stated to be a lucky star.
