Sylphya Ruhans

Sylphya is a Holy Knight, serving the War God Marsterria, and one of the main characters of Princess General 2. She is mother of Sylvain, who is Lyphia's father.

Princess General 2
She fought against Louie Marshrun and after defeat, sympathized with his ideals of coexistence between humans and Dwellers of the Dark and fought alongside him. Because of this, she was excommunicated from the Marsterria's church.

Battle Goddess Verita
Slyphya is pregnant at the beginning of the Battle Goddess Verita and bears Louie a son, Sylvain during the course of the game.

Several years after the birth of her son, the pope of Marsterria's Church passed away, and Kineriusu (キネリウス) the Third took his place as the new pope. Kineriusu gave Luna Clear the ask of reclaiming apostle status from Sylphya. Sylphya accepted her death gracefully; her main regret being her inability to see her son grow up when Luna unhappily completed her task. Since Sylphya had long outlived a normal human's lifespan, she turned into sheaf of light particles along with her holy powers, and vanished from the world of the living.
