In 1340 of the Shire Reckoning, a year before the Quest of Erebor, Middle-earth slumbers in ignorance of approaching calamity. Smaug dreams atop his golden mountain, Thorin Oakenshield roams the untamed lands, and the Shire remains untouched by wizardry. Then an enigmatic human materializes—lost, disoriented, wielding an impossible tool: the MC System. Reality transforms in his wake. Colossal keeps materialize from nothing. Boundless fields of amber grain blanket the earth. The savage borderlands morph into a landscape of redstone mechanisms, geometric precision, and cubic perfection. Legends emerge of the "Block Wizard"—a leather-clad figure who fells trees with his fists and manifests wonders through empty hands and luminescent crafting altars. Seasons turn. When Mordor's legions surge across the realm, their war machines stall before an unnatural river that violates the laws of nature itself. Their commanders gaze upward—and witness the sky itself descending as a cataclysm of water.
