The Mittu star system enjoyed a long period of prosperity, and was watched over by three powerful beings who shared their unique skillsets and technologies across three worlds for millenia. From out of nowhere, a Demon Army of immense power appeared suddenly and began invading these planets, slaughtering countless innocents and causing fear and paranoia in the godlike rulers of each world. On the planet of Altair, the first spacecraft in Mittu's history has been constructed, with the hopes that its crew can find something in the Mittu star system to end the war against the Demon Army.
