The Horn of Eld is the personal horn of Arthur Eld. It was passed down the generations until it reached Roland Deschain. Originally, the Horn was lost in the battle of Jericho Hill. Roland had given the Horn to Cuthbert Allgood, who blew it until he died. Roland neglected to obey his friend's final wishes and left the Horn at Jericho Hill. Upon the resumption of his quest to reach the Dark Tower, Roland is once again in possession of the Horn. In this iteration of the cycle, Roland remembered to retrieve the Horn at Jericho Hill. His possession of the Horn may be a sign that Roland is closer to his redemption.
