Mirror of Ur-Zababa

Wondrous item, very rare

This bronze mirror was crafted by Belic-tikal, chief smith of the king, Ur-Zababa of Kish. Sargon, the cup-bearer of Ur-Zababa, told the king of a dream he had in which the goddess Ishtar came to Ur-Zababa and killed him. Frightened by this omen, Ur-Zababa ordered Sargon to deliver a message to Belic-tikal where a cunning trap had been laid. Sargon was warned by the goddess Ishtar and instead lured UrZababa to the temple forge. There, he pushed the king into the face of the mirror and Ur-Zababa fell through, becoming trapped in a dimension of reflections forever.

When a creature is forcefully pushed into the mirror, they must make a DC 20 Charisma saving throw. On a failure, they fall through the mirror and are transported to a dimension of reflections. The world exists there in a static state and no other mortals naturally reside there. Anyone trapped within can communicate freely with those outside it. If the mirror is destroyed, the dimension within vanishes and all within perish. Only one creature can reside within the mirror at a time. If another is forced in, they are unable to cross the threshold. The creature within can be released through magic that allows transit across planes.
