Yomen's Atium Bead

Yomen's Atium Bead first appears in The Hero of Ages as a seemingly ordinary bead of atium held by the obligator-turned-governor Yomen. Throughout the novel, the bead becomes a pivotal object of deception and revelation, ultimately revealed to be a fake that Yomen uses to manipulate both his enemies and allies. Its true nature as a piece of atium-electrum alloy exposes the limits of even the most powerful Allomancers and forces characters to confront the difference between perception and reality in the final stages of the Catacendre.
