Quellion's bronze spike

Quellion's bronze spike, a Hemalurgic implant piercing his upper arm muscle and concealed by clothing, emerges in 'The Hero of Ages' as the key to his ability to sense and burn atium, marking him as a survivor of the Steel Ministry's experiments. This spike underscores the Citizen's rise as a false prophet in the chaotic post-Skaa rebellion world of Urteau, where he wields Inquisitor-granted powers to enforce his puritanical rule. Its eventual discovery and removal by Sazed reveals the depth of Ruin's manipulations, stripping Quellion of his supernatural edge and catalyzing his downfall amid the world's impending doom.
