Soulstamp

Soulstamps are the signature tool of the Forgery magic system, allowing skilled practitioners to rewrite an object's or person's history by stamping them with specially carved metal seals. First introduced in The Emperor's Soul, they evolve from a localized art practiced in the Rose Empire into a cross-world phenomenon by the time of The Lost Metal, where they are adapted to interact with Scadrial's Allomantic and Feruchemical metals. Their power to alter identity, memory, and even magical abilities makes them both a tool of espionage and a dangerous wildcard in the broader Cosmere conflict.
