Being perfect is something Sameth has never figured out how to do. Ellimere knows how to perfectly command the court and present an image of the loved and ruling Heir.
In the forge, Harath taught him that what makes great metalwork isn’t perfection but understanding what cannot be controlled.

In the end what’s created will always be itself and that is his perfection.
