On the deserted western shore of the Undying Lands and facing the Encircling Sea and the Walls of Night are the Halls of Mandos where, in lore of the Eldar, the spirits of slain Elves are called to inhabit the Hall of Awaiting, until the summons of Iluvatar at the time of the World’s End. This is the House of the Dead, the vast mansions of the Vala Namo who is also called Mandos, the Master of Doom, who knows the fate of all. He is the stern Judge of the Dead, who only once felt pity, when Luthien sang to him. His wife is called Vairë, the Weaver. His brother is Lórien, the Dream-master and his sister is Nienna, the Weeper.
