In the Outer Rim, a lawless region of space filled with violence, a young girl vows vengeance against the marauding pirate bands who brutally murdered her family.

After enlisting with the zealous matriarchal Ashna Maidens who attempt to police the Outer Rim, Serah'Elax quickly becomes a powerful weapon.

Meanwhile, a ruthless pirate band has taken over a cruise ship deep within Alliance space. They run into unexpected trouble when they encounter a few members of the highly trained force of military specialists known as the Founder’s Elites, who happened to be vacationing on the vessel. Disturbed by the boldness of the pirates, the Alliance tasks the rest of the Founder’s Elites with dealing a powerful blow to the marauders, who normally operate in the Outer Rim, once and for all. However, they quickly discover that things in the Outer Rim are not as expected.

The young warrior and Founder’s Elites must come together to face an extradimensional threat left over from the Rift War that seeks to turn the last bastion of safety in the Outer Rim into something that could threaten the entire Twin Galaxies. Will the new allies have the cunning necessary to defeat this insidious threat or will it tear the Ashna Maidens apart from the inside?
