333 Gems of Tharizdun

In the year 2022, a small band of misfits named The Mighty Menagerie came across a brass orb given to them by Bast , this was the Orb of Toriil.
When they learned of what was inside this brass orb they also learned, thanks to the Elder of the Dawngreets and her Elder's Glove of Lore that this is one of the 333 Gems of Tharizdun and it can spell trouble for all of existence.
Currently it is believed these orbs are the gems, and a few have been "discovered"

History

Sas currently holds two such orbs, one is Orb of Toril (housed in the Bast's Brass Orb) and the other one is breaking apart and they have not discovered it's world.
They had heard that Bargle had one to Mystara, which was found by the Fortunate Mead Heroes and seems to be in the possession of Lars Heyton and Ursa. They also seem to have the one Pradam Estorich had in his magic hat... This one is not fully known by the Menagerie.

Significance

These artifacts are not known to most, but they house a world in its final days. Each seems to come about as Tharizdun finds ways to corrupt those in the world to perform the necessary ritual to "preserve" their world in the final days, whenever that may be. It is done in exchange for great power and knowledge.
