Get ready to cross the wall. Planet Iltrasor no longer rotates and from space two great walls are visible. These walls separate the eternal night from the ever light, Lightside and Darkside, and also separates the two unique races found therein. Lightsiders are ruled by a General, the Darksiders have an Emperor, and a third race moves in from the northern pole, the Spiners, with their leader the Hive King. Lightsiders and Darksiders form the Light-Dark Coalition Force to stop the Spiner onslaught. The Special Forces teams require Operators, Lightsider Intelligence agents who can assist the teams during missions against the Spiners using the most advanced technology on the planet. Some of these Operators might get lucky and work with Darksider Special Forces, but they often don't live very long. Tiria, a Lightsider Intelligence Officer, is promoted to the LDCF and becomes an Operator for a Darksider team known only as Alpha Squad. During one mission, Tiria faces a life-changing decision that will launch her into another world and the only people she can trust don't trust her. There is lumination on Darkside and shadows on Lightside. Finding them will result in life or death for Tiria and Alpha Squad.
