Yomen's Atium Bead

Yomen's Atium Bead emerges as a pivotal artifact in Mistborn Book 3, The Hero of Ages, representing the last known reserve of the godlike metal atium in the Final Empire's collapse. Guarded by Obligator Lord Yomen in the fortified city of Fadrex, it symbolizes the desperate scarcity of Preservation's power amid Ruin's rising dominance. Its ultimate fate underscores the series' themes of sacrifice and hidden legacies, tying directly into the cosmere's broader atium mythology.
