After dying in a tragic accident, Joseph Locke awakens on the magical world of Haven in a healthy, powerful body. He discovers he is a void mage—the rarest magic user on the planet—capable of piloting giant steampunk mechs called Titans. Joining an all-female airship crew, Locke embarks on high-stakes mercenary contracts while adjusting to his incredible powers and a ghost living in his machine.

Joseph Locke is a former paralyzed Earthling who embraces his second chance at life with boundless enthusiasm and gratitude. As a void mage, he balances his explosive magical potential with a fiercely protective loyalty to his crewmates. He is a confident, humorous captain who commands respect while deeply valuing the women who stand by his side.

What begins as simple mercenary bounties and ruin expeditions quickly escalates as Locke and his companions uncover ancient secrets about Haven's past. From hunting corrupted dragons to rescuing crewmates from moon cultists, the team constantly upgrades their mechs for tougher battles. Ultimately, Locke leads his companions on an unprecedented voyage into outer space to defeat a world-ending deity.
