Linchpin Spike

The Linchpin Spike emerges in Mistborn Book 3 as a pivotal artifact in the intricate web of Ruin's control over the world, designed to anchor the prison of the godlike force and prevent its full release. Though scarcely detailed, it represents a critical linchpin in the cosmology of Scadrial, underscoring Preservation's desperate measures against Ruin's encroachment. Its role culminates in the cataclysmic events of The Hero of Ages, where the fate of the spike intertwines with Vin's ascension and the harmonious reconciliation of opposing powers.
