Well of Ascension

Well of Ascension appears in Mistborn.

The Well of Ascension, a mythical cavern at the heart of the Final Empire, serves as the pivotal locus of power in Mistborn Era 1, evolving from a whispered legend in the first book to the climactic battleground in the second. In 'The Well of Ascension,' it reveals itself as the source of Preservation's power, where Vin confronts the full scope of Ruin's manipulation and the true nature of the Shards. Its destruction marks a turning point, unleashing raw power that reshapes the world and sets the stage for the trilogy's apocalyptic finale.
