The five hundred year Thouron War is over.

The war weary inhabitants of the planet Progensha have finally entered an era of peace, but a newly discovered portal brings the Alliance-GSE War dangerously close to Progensha. It threatens to destroy everything the Uderrans and their allies have fought long and hard for.

A dark secret the GSE has been hiding is revealed, and could be the beginning of the end of everything. A new and powerful force has information and a possible way to tip the balance of power, but it will mean the destruction of the Infiltrator.

Captain Vee is forced to choose sacrificing herself, her ship, and her crew on a gamble to save two universes.

Meanwhile, Leahcim, T'oann, Markka, Cora, and their friends find themselves preparing to fight a war against an enemy they cannot win against alone.

The coming final battle will forever shape their destinies-if they survive.
