In a world where magic is no longer stable, power comes at a cost... and balance is everything.

After surviving the chaos of the Vein of Hell and the rise of Lucifer's generals, the Zodiac heroes now face a far greater threat-something older than gods, deeper than magic itself.

The First Magic is awakening.

As the fabric of reality begins to collapse, the very powers that once made them strong now threaten to destroy everything. Stars fall, elements rebel, and the Constellation that once guided them begins to shatter.

At the center of it all stands Kael-changed, evolving, and dangerously close to becoming something beyond human. Hunted by forces that seek to reclaim what he has become, he must decide whether to fight, surrender... or redefine what power truly means.
