Linchpin Spike

Linchpin Spike emerges as a pivotal Hemalurgic artifact in the Mistborn series, first appearing in The Hero of Ages as a critical component in the Lord Ruler's grand design. This specialized spike serves as the metaphysical anchor that binds together the fragmented consciousness of the god Ruin, preventing its full manifestation until its removal. Its significance transcends mere magical artifact, representing the delicate balance between Preservation and Ruin that defines the series' cosmology.
