The Humble Sisters of Eluria from Vargtroms Studio and Roman Volkov is a prequel branch from the main story of the last shooter Gilead's campaign - Roland Discane to the Dark Tower. Events in Eluria take place after the tragedy in Medjis, described in the fourth book "The Sorcerer and the Crystal," but precede the first part of the "Shooter" of the "Dark Tower" cycle.
