Years prior to the game's events, Dean received orders from Arion to protect the latter's fiancée, Linoan. Pleased by the trust that Arion placed in him, Dean abandoned the Thracian army to fulfill his commands. After rescuing Linoan from the captivity of the Grannvale Empire, he protected her from many assassins hired by the Empire and cheered her up whenever she was about to break down. Dean falls in love with Linoan, and although she requites his feelings, they never marry due to Dean's loyalty to Arion.
Dean is introduced in a conversation with Glade at the start of Chapter 13. He also explains the tactics of fighting on a dragon to Eda, who recklessly offered to engage the enemy alone, despite the presence of ballistae.
In the conversation between Eda and Linoan at the start of Chapter 14, it is mentioned that Dean feels uncomfortable at meetings and therefore avoids them. It is also stated that Dean laughed whenever Linoan assumed that he was a well-known mercenary before discovering that he works for Arion. During the chapter, he can visit the southwestern house and meet with Altena, who orders him to accept the Dragonpike as a gift from Arion so that he can better defend Linoan. If Linoan is killed or captured during Chapter 14x, Dean will leave Leif's army and return to Thracia.
After Manster is recaptured by Leif, Dean reveals his intentions of returning to Thracia. However, Linoan makes an attempt to stop him, and despite viewing her behavior as childish, he decides to remain at her side for the duration of the war.
In the ending, Dean accompanies an injured Arion to back to Thracia. He later becomes the commander of the New Kingdom of Thracia's Dragon Knights.
