Luke was born in Westport, Connecticut to Hermes and May Castellan, a mortal who had the ability to see through the Mist. As a baby, his parents took him with them to Camp Half-Blood, where May wanted to host the Oracle. Right before entering the big house, she gave her squirming baby son to Hermes. Shortly after, a green glow lights up the house's windows, and a terrified Hermes hands baby Luke to Chiron and tried to save May, but was too late, due to the horrible curse that Hades had placed upon the Oracle.Luke Castellan is a 19-year-old demigod (in The Lightning Thief), the son of Hermes and May Castellan. Introduced as the friendly head counselor of the Hermes cabin, he is soon revealed to be a servant of Kronos. Luke is resentful of his father, who adhered to the gods' policy of non-interference despite May Castellan's mental illness. Luke runs away from home young and eventually arrives at Camp Half Blood. After the loss of Thalia, a failed quest, and continued silence from his father; his ongoing resentment turns into a strong hatred of not only Hermes, but all the gods. Though described by those who knew him before he joined with Kronos as a nice guy, he later becomes moody and violent.
