In End-World, Roland encounters a future version of himself as an adult. Alain and Cuthbert cross a dilapidated bridge with Roland's lifeless body, though at the cost of Cuthbert's horse, whom Bert is forced to euthanize, before destroying the bridge to elude the posse. In the dream-like realm of End-World, Marten Broadcloak taunts Roland with the assertion that it is he whose machinations led to Roland's situation, and will lead to his eventual death. This act gives Sheemie the gift of telepathy, teleportation and rapid healing. The robot appears to electrocute Sheemie, filling him with energy in order to 'experiment' on him.

Meanwhile, a hapless, mentally challenged child named Sheemie, the village idiot of Hambry, and a friend of Roland, comes across a military control center called a Dogan (featured in the novel Wolves of the Calla), where his presence reactivates a long-dormant robot. Alain and Cuthbert continue fleeing, carrying the unconscious Roland with them, barely escaping their pursuers via a dangerous river. There he encounters the spirits of the deceased Big Coffin Hunters. It transmogrifies into an enormous eyeball with tentacles that attach to Roland, drawing out his consciousness and into the sphere's dream-like realm, called End-World. The young gunslingers argue over Roland's insistence on carrying Susan Delgado's body to give it a proper burial, and during this, Roland shoots the Grapefruit. In continuation of the events of The Gunslinger Born, Roland Deschain and his ka-tet, Alain Johns and Cuthbert Allgood, are on the run from the Hambry posse, hoping to return to Gilead with Farson's prize, the evil seeing sphere known as Maerlyn's Grapefruit. On March 5, 2008, David and Lee appeared at a midnight signing of the first issue of the series at Midtown Comics Times Square, as they had done the previous year with The Gunslinger Born. The series is written and illustrated by the same creative team as The Gunslinger Born, which includes writers Robin Furth and Peter David, and illustrators Jae Lee and Richard Isanove. Whereas The Gunslinger Born was largely based on the events of The Dark Tower IV: Wizard and Glass, The Long Road Home showcases mostly new material not found in any of the novels.

The story depicts the title character of Roland Deschain as he returns to Gilead from Mejis. The first issue was published on March 5, 2008. Stephen King serves as Creative and Executive Director of the project.

It is plotted by Robin Furth, scripted by Peter David, and illustrated by Jae Lee and Richard Isanove. It is the second comic book miniseries based on Stephen King's The Dark Tower series of novels. The Dark Tower: The Long Road Home is a five-issue comic book limited series published by Marvel Comics.
