Ian Shlasko: 4 books

When armies can invade solar systems and magic can destroy planets, only the Xen Guardians can preserve the peace. As a new enemy emerges, Prince Xentor prepares to take on the burden of his ancestors. He will not be alone.

The defeat at Aeos may have left the Empire wounded, but an animal only becomes more dangerous when cornered. While the Guardians revel in their victory, their greatest enemy prepares for a showdown that will shatter the Frame, and may destroy the magic forever.

The battle has ended, but the war continues. New enemies emerge, but the old ones are not forgotten. Alliances crumble under the weight of impending peril, and even the Guardians can no longer keep order. Still, the Sentinels persevere. Their methods differ, but their power is unmistakable. The only question is whether they'll save the Frame... Or destroy it.

The war is over, but even victories have consequences. While the factions recover from the years of conflict, and prepare for the changes ahead, long-forgotten enemies have returned to reshape the Frame in their image. The Guardians may be the only ones capable of saving the Frame from this menace, if they can first save themselves.
