Zwei: The Ilvard Insurrection (v2018.01.22)

Pilot, treasure hunter, and courier Ragna Valentine lives a life of adventure flying the high skies of Granvallen. But on a routine delivery to the remote floating continent of Ilvard, he finds himself ambushed by two dragon-riding ne’er-do-wells who send his plane spiraling to the ground. Fortunately for Ragna, his crash was witnessed by someone in a position to do something about it: vampire princess Alwen du Moonbria. Pulling the dying Ragna from the wreckage of his plane, Alwen forms a blood contract with him, saving his life in exchange for his services as her vassal.
