Sean is a physical fitness devotee and practicing vegan. He is in excellent physical shape and has tan skin and blonde hair, he is quick to mention that his ears are slightly pointed. Testing shows that he has some Fae blood in him.
Sean is a reluctant soldier, and was a pacifist prior to his encounters with the Orientani. Since Team 098 has started to encounter demonic forces he has become a more willing member of IS51. He enlisted at the same time as his associates Tasha Jade Munroe (File # 79018) and Kameron Wolfe (File # 79013), he acts as the spiritual guide for his associates but they both tease him about his overly strict code of conduct.
Sean has come into conflict with fellow team members Franklin Norris (File # 24120) and Jonathon Lamond (File # 79215) because of his prudish behaviour.
