Roland Deschain, son of Steven Deschain, was born in the fictional Land of Gilead. Roland is the last gunslinger, charged with finding the Dark Tower. This quest is obsession, monomania and geas to Roland: the success of the quest is more important than the lives of family and friends. He is a man who lacks much imagination, and this is one of the stated reasons for his survival against all odds: He can't imagine anything other than surviving to find the Tower.
