Years after the Battle of the Five Armies brought fragile peace to Middle-earth, a distant echo of darkness begins to awaken beneath the Lonely Mountain. Deep within Erebor, ancient halls tremble once more, stirred by whispers of a forgotten evil—an unseen remnant of Smaug’s wrath that refused to die with the dragon.

Drawn from the quiet comfort of the Shire, Bilbo Baggins is summoned again to a world he thought he had left behind. Joined by Gandalf the Grey, and the ever-watchful Elves Legolas and Tauriel, Bilbo embarks on a perilous journey through reborn kingdoms and scarred lands, seeking the truth hidden in the depths of the mountain. What they uncover threatens not only the Dwarven realm, but the balance of power across the East.
