Letalis tells not a fantastical tale on the well lies of war. It is but a candle exposing every human sin in this world or another. Sharing the presence of weaving drama, spun around the intricacies of ambition and greed, to the adventures of the daring.

The warring states of this day are warming around the new fires of a grand war, freed from half a decade in shackles of so-called peace. On such seven great lands and seas of deranged humanity are all but controlled by two elements. Eifer and kei. They give birth to the wrath of the species. In life. In battle. And had bred new sin. With the ever growing threat of the prosperous Confederate titan looming over Yurupe, the ailing alliance of Aelon lies on an endless path of futile resistance in the face of the vastest invasion. Of the billions, Arminius Reichner, a schoolboy, is trapped in the casing of shells and corpses. There is but one exit. That is into the pits of No Man's Lands. For every sane person desired the praise of heroism they would endure for the people of their kingdoms, none knew how a childish dream would shatter the most resolute of minds. Victory has become a forgotten word. In a cruel world called paradise, hell sits not so far.
