A Promotion is a chess rule describing the transformation of a pawn that reaches its eighth rank into the player's choice of a queen, knight, rook, or bishop of the same color.[citation needed] Since the most powerful piece in the board is the queen, it is often the piece that is chosen for promotion. This is an analogy to Millia's sudden inheritance of the kingdom of Turan after the death of her sister Liliana.

This is an analogy to Millia's sudden inheritance of the kingdom of Turan after the death of her sister Liliana. In a flashback, Luscinia brings Liliana to Iglasia after its demise. Liliana wants to avenge her father but Luscinia warns her that killing him will only lead to a massive civil war in Ades that decides who will take over as Premier and the Exile nations will use the war to their advantage. Nevertheless, he allows her to kill him if she promises she can bring peace to the world. Realizing he is right, Liliana joins Luscinia's cause. In the present, both sides' fleets mourn the death of Liliana; as Dian and Magnolia are thrown in jail, which the former regrets, realizing the consequences of her actions. Millia apologizes to her late sister for being naive for not understanding why she joined Luscinia. Fam also realizes how naive she was in thinking peace could make people forget their hatred. Luscinia and Alauda gives their condolences to Liliana as well and tells Fam and Giselle to stick to their dreams and protect Millia as that was Liliana's last wish. With the peace talks a failure, Luscinia and Alauda enact their final plans. The 1st and 2nd fleets suddenly depart, much to the rebels' confusion. Alauda and his assassins attempt to kidnap Al again at the Silvius but Dio kills him. Meanwhile, Luscinia attempts to take Sara with him. Vasant tries to stop him but she ends up being killed by him. As Luscinia brings Sara to Northern Glacies, Sadri and Kayvan's fleets prevent Orang's Third fleet from going after him. Fam apologizes to Millia for her selfishness and vows that she and Giselle will help her anyway they can. After arriving at the "Ancient Goddess", Luscinia bows to "Maestro" Sara and recites a Mysteria, revealing Sara also can activate an Exile as her Exile, the Grand Exile, is buried there. As the Grand Exile takes off, Luscinia activates its powerful beam cannons miles away from the battle zone, and the Sky Pirates witness the destruction of both the Second and Third fleets.
