On the aethership's maiden voyage, Seraphin and the Knights of Aether had prepared for everything---except treason. The villainous chamberlain wants to overthrow King Ludwig and claim the electro-aetheric technology for Prussia. The only escape for the king and his companions lies in the frosty skies above Bavaria. The ships first flight is a success, but their respite is short-lived. As long as the chamberlain is free to spread his lies, these travelers will find no safe harbor. To save the king's throne, they must push the ship even fartherout of the sky...and into the stars!
