Ophelia is the daughter of Odin. Like the other children in Fates, Ophelia was placed in the Deeprealms to protect her from the war.
In her Paralogue, Ophelia ventures out of the Deeprealms to the Ancient City seeking "The Super-Ultimate Tome" that she read about in her father's notebook. As fate would have it, she bumps into her father who had come to buy tomes from the city as well. Unfortunately, their reunion is cut short by bandits who are pillaging the village. Ophelia and Odin go off to confront them and eventually dispatch the bandits. After the battle, Odin informs Ophelia that the tome she was seeking did not exist. The notebook she had read was not a list of powerful tome, but rather, weapon names he created on his own. Though Ophelia is disappointed, Odin hands her a tome he had bought for her while they were in battle. Since the tome had no name to it, Odin tells Ophelia to give it one. Without a second to even think, Ophelia decides to name it Missiletainn, a name she saw in the margins of the last page of Odin's idea book. Even though the book said that the Missiletainn sword was a crummy weapon, Ophelia loved the name nonetheless. Odin admits that it is the only name he has ever given to a real weapon. Odin asks his daughter to join his army, a request Ophelia happily accepts and the two vow to walk forward together as the "chosen two".
