Bones Past (The Relicant Chronicles)

The final chapter in the epic saga!
The Relicant Empire has suffered massive turmoil of late, including invasion attempts, shadow assassins, skeletal armies, and an attempted coup. Now, however, things seem to be settling down. Which gives Emperor Hibikitsu and his new Rojiri time to discuss matters and make plans.
Except that a new threat is brewing, something no one could have expected. A terrible power, deeply rooted in the nation’s past.
To combat it, Noniki, Kagiri, and the rest must fend off a monstrous new force while delving into the mystery of how the Relicant Empire came to be—and hope they can find the answer in time to save what it could become.
At the same time, a hidden danger lurks, poised to destroy everything and plunge the kingdom into a darkness from which it might never recover.
Can Rimbaku survive and forge a new path? Or will it perish forever?
