In the ancient city of Caldera, a place where magic and technology coexist, Kael Straven is a hunter of rare artifacts. Once an elite Guardian tasked with protecting the city's magical relics, Kael now works as a freelancer after being dishonorably discharged for a crime he didn’t commit.
When Kael is hired to find the Aether Key—an artifact said to unlock the lost city of Veridion, a source of untold power—he sees it as a chance to clear his name. But the job isn’t simple. A shadowy cult, the Veylos Covenant, also seeks the Key, willing to destroy anyone in their way.
As Kael uncovers the artifact’s secrets, he discovers that it’s tied to his own past—and that its true purpose could either save or doom the world.
