Kunwu

Kunwu was a legendary smith in Liyue who forged Solar Pearl, Dragon's Bane, and Lion's Roar.
Originally a scholar who intended to gain admittance to Sumeru Academia in the pursuit of knowledge, Kunwu changed tracks upon coming into possession of the Sundial of Enduring Jade.
Upon discovering he could find no flaws in the sundial's design, he decided to become a craftsman himself in order to challenge its designer, Morax, and create an item as equally flawless.
