Lione. The Falling City, #1

She seeks to bring down the Lionian Sovereignty. He is determined to save it. Aurion Illica is proud to be a councilman of the Lionian Sovereignty. But as corruption taints the Council, assassinations shake the Sovereign's power, and the rebellions of the slave races, particularly the Nurmi savages of the Corelands, threaten to extinguish the greatness of Lione, Aurion must choose between Lione and his life.
Lania is a Warrior of the Nurmi, one half of the religious incarnation of prophecy. It is she who will destroy Lione and free the world from the monsters of the south. As they cross paths, Aurion begins to see that the Nurmi are not mere savages to be enslaved, and Lania is forced to recognize that not all Lionians are faceless conquerors to be slain. It is only by working together that the two mortal enemies may save both peoples in this time of great upheaval.
