Beneath the forests, mountains, and cities of Valdoria, a secret empire stirs. Unseen by the rest of the world, a network of tunnels, workshops, and hidden fortresses begins to rise—an underground kingdom forged from Nightsteel, shadows, and ambition. Khalael, tasked with overseeing the construction, watches as miners, smiths, and fletchers shape weapons, arrows, and armor of unparalleled power. Every stone laid, every forge lit, every arrow fletched strengthens the continent's hidden might.
