In the war-torn world of Pangea, strength is measured by Soul Aura — the mystical force tied to spirit animals. At just nine years old, Nox Harrow awakens something ancient, something deadly: the Black Jackal. Now forced to flee his home, Nox trains under a legendary monk to master his soul aura and uncover the truth behind his power. But as enemies close in and allies hide secrets, Nox must decide what kind of warrior he'll become — and how far he's willing to go to protect the ones he loves.
