The last Gunslinger, Roland Deschain, has been locked in an eternal battle with Walter O'Dim, also known as the Man in Black, determined to prevent him from toppling the Dark Tower, which holds the universe together. With the fate of the worlds at stake, good and evil will collide in the ultimate battle as only Roland can defend the Tower from the Man in Black.

Gellert Grindelwald has escaped imprisonment and has begun gathering followers to his cause—elevating wizards above all non-magical beings. The only one capable of putting a stop to him is the wizard he once called his closest friend, Albus Dumbledore. However, Dumbledore will need to seek help from the wizard who had thwarted Grindelwald once before, his former student Newt Scamander.

Before he lost his sight. Before he pledged his service to Kublai Khan. Hundred Eyes saw what made him into the deadly assassin who trains Marco Polo.
