Encountered only by those who have journeyed far beyond the boundaries of the world into the labyrinth of Valknut, the Unmaker is a Dragonborn smith who works a magical forge in the ruins of an ancient city. Little is known of the being's history bar that the city it inhabits is called Tesseract and that some terrible crime befell it.

The Unmaker seems obsessed with perfection and has filled its prison with perfect examples of mundane objects, weapons and even concepts. It treats humans with the contempt common to its race, but does not attack them on sight - though it does seem to have developed a particular hatred for certain of those who have encountered it.
