Luxon beacon

A  is a sacred relic from the Xhorhasian Empire. One of these very powerful magic items had been stolen by wizards from the Dwendalian Empire and was in the care of the Soltryce Academy in Zadash.

Description
This cannonball-sized dodecahedron had handles on two sides, and emitted a dull undulating grey glow.

When Caleb cast Identify on the object, he found the magic contained within was alien and of a level of understanding outside of what the spell could provide. As he focused deeper on it his brain began to open up into another space of what seemed to be an expanse of an endless infinity of nothingness.

Thuron claimed that the Beacons allowed Xhorhasians to live many lifetimes, and those bound to it to be reborn having their souls and memories retained within the Beacons.

Thuron: "The beacon is part of our culture. The beacon allows the rebirth.

Molly: The rebirth of what?

Thuron: Of our people."

"As long as the Beacons remain, me and my people will live more." "The souls continue. With each rebirth, the memories retain." "We live. We worship. We learn. We die. We are reborn until we are perfect."

History
Thuron stole the Beacon from the Hall of Erudition in Zadash as part of a detailed plan from the Empress of Xhorhas, Leylas Krynn. It was taken from him when he was killed by the Crownsguard in the Sewers. While the Crownsguard were carrying it off towards the King's Hall, Caleb used magic to steal the Beacon and Nott created an illusory version of it that she made disintegrate in midair.

The Mighty Nein later bought a lead lined box to hide the beacon within. They stashed it inside Jester's haversack.
