In the gritty port city of Quilia, those with wings have all the power. As for scrappy thief, Riff, he's flightless. He's embarking on the biggest heist of his career, and this time, the stakes are personal. His sister lived and died honorably, yet his impoverished family is about to lose their home and her final resting place. Making matters worse, his old mentor denies him entry to his elite thieving guild, shutting the door to lucrative jobs. So, Riff assembles a crew and takes on an ambitious tech heist to literally save the farm-aiming, while they're at it, to topple the city's oppressive classist hierarchy, which stretches all the way from the thieves' guilds to the top echelons of society.
