The [Withering Era] arrives. Interstellar spores wipe out civilizations, while mutated crystal beasts roam the surface. Ling Yue, the lowest-ranking maintenance worker in the Lighthouse Federation, carefully hides a secret: she can faintly sense the deadly spores. This is a mark left by a failed experiment at Eden, and a reminder of a past she'd rather forget.
Li Jin, the Federation's youngest dragon-rider commander, is cold, formidable, and devoted to order above all. During a crystal beast invasion, Ling Yue's unnaturally calm reaction catches his eye, stirring suspicion and curiosity. Forced to venture together into perilous territory, they face powerful enemies and come close to death. Li Jin discovers that this seemingly delicate woman is the key to unraveling Eden's apocalyptic conspiracy.
When hidden secrets come to light and trust is put to the test, the cold commander and the girl who was an experimental subject forge an alliance in the desperate wasteland. Ahead lies the shadow of spores covering the globe; behind them, the Federation's upper ranks close in at every turn. They must join forces amid the ruins to find humanity's last glimmer of hope.
A story of destruction and hope, coldness and tenderness, and people saving one another in the apocalypse.
