Last Exile: Fam, the Silver Wing

Description of anime Last Exile: Fam, the Silver Wing

"I've made up my mind! I'm going to steal that ship!"

All source of life originates from the Grand Lake.

At this very sacred lake, the battle between the Ades Federation and the Turan Kingdom has just begun. The Ades Federation, armed with massive battleships and its sights set on conquering the world, declares war on the Turan Kingdom. With the Federation's troops encroaching on their beloved country, Turan now lies on the brink of collapse. As this is happening, the princesses of Turan look on as a small vanship named Vespa cruises above their heads.

"We shall now commandeer your flagship and take her from this battlefield. The choice is yours. Die here, or survive with us Sky Pirates!"

The Vespa continues to weave through the barrage of bombs, while the fleets of the Federation close in on Turan.

What are the motives of Luscinia, the man leading the Ades Federation into the war? And what is the secret behind "Exile"?
