In a near future, humanity has formed a loosely structured world government where all affairs are managed by an international AI network known as Sapientia. Citizens lead peaceful lives by faithfully adhering to its rational directives. However, Sapientia's lunar development initiative, which exiles criminals and pollutants to the Moon to preserve Earth's tranquility, generates inequality and poverty on the lunar surface, igniting a spark for war. Jacob "Jack" Shadow becomes entangled in this conflict after his family is killed in a terrorist bombing carried out by the Moon's rebel army. Swearing vengeance, Jack enlists in the Earth army as a scout on the Moon, only to uncover an unexpected leader within the resistance forces.
