For centuries the Avalon Orbital Ring has hung over the untamed world of Brecilien. For centuries its noble mechanized knights have descended upon the planet to battle the giant Beasts that roam its surface. Mod, a poor skyfisher, dreams of joining their illustrious ranks and piloting a mech frame to earn honor, glory, and enough wealth to dig their family out of the Orkney slums.
Those hopes are dashed when their family's ship is cut down by High King Arthur Pendragon.
Injured and alone, Mod is approached by a mysterious woman who offers them a chance for revenge. But vengeance will come at a steep cost.
To infiltrate the court of Camelot and kill Arthur, Mod must delve into the darkness at the heart of Brecilien, uncover dangerous secrets long buried, and ally themselves with shadowy forces intent on furthering their own agendas. They must sacrifice their very name and become the villain that legends say will bring about the fall of Avalon.
They must become Mordred.
