Atium Bead Disk

The Atium Bead Disk first appears in The Well of Ascension as a mysterious metallic artifact whose significance is only hinted at through its absence of description. Across the Mistborn series, this unique form of atium evolves from an enigmatic object into a pivotal element in the metaphysical and political struggles of Scadrial. Its presence marks critical turning points in the balance of power between Preservation and Ruin, and its eventual fate intertwines with the fate of entire civilizations.
