He is a Greek demigod, the head counselor of the Apollo Cabin at Camp Half-Blood, and the camp's premier healer.


compassionate, laid-back, and pragmatic head counselor of Apollo’s Cabin. Often viewed as a "ball of sunshine", he balances a warm, empathetic demeanor with fierce protectiveness, acute medical stress, and a tendency to overwork himself as Camp Half-Blood's primary healer.
Warm and easygoing, but slips into brisk, clinical directives when someone’s hurt; uses gentle humor to calm tension.
