"Those who dwell in the past risk losing sight of their future."
Curiously enough, the second-in-command of the Temple Knights originally came to Ishgard as a clandestine agent of Garlemald, with orders to seize any Allagan artifacts that the Holy See might have hidden within their reliquaries. While she successfully infiltrated the Vault disguised as a female acolyte, she failed to conceal her identity when questioned by a young Temple Knight—Ser Aymeric.
In an unexpected display of mercy, Ser Aymeric, knowing full well that her crimes were punishable by death, offered to spare her life should she pledge to serve him. The Garlean spy agreed, if only to see another day, and with every intention of running away when the opportunity presented itself. Yet after lengthy discussions with Ser Aymeric in which he professed visions for sweeping reform, Lucia was so inspired by his idealism that she chose instead to honor her pledge and serve as his right-hand.
However, there are some points on which the twenty-eight year old woman and Ser Aymeric do not see eye to eye. Despite his best efforts to instill in her a joy of cooking by teaching her his original recipe for dodo omelets, she remains thoroughly uninterested in the culinary arts.
