For centuries, the Ashen Order has protected the people of Darencia from monsters. Celeste, a young squire in the Order, is sent to the port town of Ancora to prove herself worthy by retrieving an ancient artifact that has corrupted the nearby forest.

When a mysterious young woman steals the artifact before Celeste can take it, she fails her initiation. Determined to prove herself, Celeste leaves home to find the thief, reclaim the artifact, and become a knight.

But the outside world is much different than the isolated society Celeste grew up in, and she joins forces with the mercenary Valana and the researcher mage Ruby. Their journey takes them across a continent filled with mysterious ruins, remnants of an ancient civilization that crumbled ages ago. No one knows who they were or why they fell, and the stolen artifact is one of the few remaining relics from their era.

The more Celeste sees of the world, the more she questions not only her mission, but also the role of the knighthood. Is it right for them to remain separate from the rest of the world? Do they protect people as much as they claim, or have they prioritized the artifacts they seek above the lives of the people they claim to protect?

One thing is certain: the woman who took the artifact is no ordinary thief, and the stolen artifact is only the tip of a dark plot. Destiny ties them together, and this journey will change Celeste's life forever.
