Moon-and-Star is a Dwarven ring of Chimer hero Nerevar. The artifact was forged by one of the smiths of Dwemer Sorcerer-priest Kagrenac and blessed by the Daedric Goddess Azura. The ring lent Nerevar supernatural powers of persuasion and indisputable proof of identity, since any other who tried to wear it would be killed instantly. The Moon-and-Star helped Nerevar unite the warring Chimer clans, and form the First Council which included the Dwemer.
Moon-and-Star played a role in the Nerevarine Prophecies, as it allowed the Nerevarine, the reincarnation of Nerevar, to again unite the Great Houses and Ashlander clans, this time in the battle against the forces of Dagoth Ur.
The ring is received from Azura in the Cavern of the Incarnate during the Third Trial of the Main Quest. See The Path of the Incarnate quest for more information.
