Mirror of Infinite Transpondence

Mirrors of Infinite Transpondence are pairs of magical mirrors that allow long-distance communication.

Appearance
Mirrors of Infinite Transpondence typically are silver hand mirrors.

Properties
The Mirror allows ten minute conversations between two parties three times per day, even if they are on different Planes of Existence. To invoke it, the holder rubs the surface and calls out the name of the person sought to be contacted. Once communication is established, the holder can turn it around to display the area and items to the other party.

Campaign Two: The Mighty Nein
Allura Vysoren gave Jester Lavorre a Mirror in preparation for the Mighty Nein's trip into the Happy Fun Ball so that the party would be able to stay in contact with her. When the party returned, Allura requested it be returned to her.

The Tales of Exandria: The Bright Queen
When Quana Kryn traveled to the Ghostlands to meet with Dryca and confirm the appearance of another Luxon beacon, Leylas Kryn watched the exchange via a Mirror of Infinite Transpondence, witnessing the party being ambushed by draegloths.

Owners
The Tal'Dorei Campaign Setting Reborn lists several individuals who own a Mirror of Infinite Transpondence that might be contacted if only one mirror is found by a player character. These people are:
 * Odessa Tal'Dorei in Emon
 * Sylker Uttolot in Kymal
 * Eskil Ryndarien in Westruun
 * Ouestra in Syngorn
 * Xundi in the Elemental Plane of Water
 * An unnamed Remnant Chosen in the Shadowfell
 * The Wonderworker in an untraceable location, presumably the Palace of Wonder

Another Mirror has no owner and is in an empty dungeon in Whitestone Castle.
