The game's story centers around a group of knights called Chevalet Blanc and how the protagonist and her knights take back the kingdom of Elesius, which is being controlled by the Council of Elder Statesmen.
Chevalet Blanc's beginnings are anything but noble: two Drifters, Clarissa Arwin and her adoptive brother Felius come to the kingdom of Elesius in pursuit of a Drifter named Rupert Dandridge, who five years ago slew Clarissa's mother, itinerant archaeologist Melissa Arwin, and took from her the powerful sword "Iskender Bey".
