Sazed's metal sheets

Sazed's metal sheets emerge as a pivotal artifact in Mistborn Era 1, where the diligent Keeper Sazed meticulously compiles the world's fragmented history, lore, and Terris prophecies onto durable metal plates using Feruchemical steelminds. In The Hero of Ages, these sheets serve as his comprehensive archive, allowing him to cross-reference ancient knowledge during the world's cataclysmic unraveling at the Well of Ascension. Ultimately, Sazed integrates this vast repository into his ascension as the harmonious god Harmony, preserving humanity's stories within his divine consciousness while physically manifesting them as the iconic metalminds that symbolize Mistborn's legacy.
