The fires of war on the northern snowfields have yet to die down, but the darkness of the Deep Abyss has already crossed the mountains and spread across the continent.
Leon, a youth who left the ancestral homeland of the Abyss-Guarding Wolf Clan, finds the Sacred Blood Wolf Clan lineage surging within him harder and harder to suppress. The brand on his back burns every night, while the Deep Abyss’s bewitching whispers never cease, constantly trying to devour his mind.
Traveling south with Isolde, who knows the ancient scriptures, he crosses lands ravaged by war. Ruined relics, abandoned ancient cities, and villages overrun by demons appear one after another. The surface is strewn with the ashes of calamity, while chaotic, mutated monsters keep pouring out of fissures underground.
Along the way, they encounter exiled tribes, city-state nobles with their own agendas, and surviving remnants of the old Abyss Guard. The truth about the lingering spirits of the Deep Abyss from a thousand years ago gradually comes to light, and the outline of a vast conspiracy buried for a millennium slowly emerges.
As Leon struggles with the pain of his bloodline running wild, he battles monsters and hones his skills, causing his Sacred Blood power to grow rapidly. But chaos does not come only from the outside. The seeds of darkness have long been lying dormant in people’s hearts.
The enemies are not just the demons of the Deep Abyss. Suspicion, betrayal, and ambition conceal deadly dangers everywhere.
When the Abyss extends its fangs into the human world, can Leon, the young Wolf King, hold fast to his heart and resist being consumed by darkness?
