Melishi is obviously a historical person in The Stormlight Archive. He is mentioned only in the Epigraph for Words of Radiance: Chapter 58. It seems that he was a Bondsmith amongst the Knights Radiant.[1]

So Melishi retired to his tent, and resolved to destroy the Voidbringers upon the next day, but that night did present a different stratagem, related to the unique abilities of the Bondsmiths; and being hurried, he could make no specific account of his process; it was related to the very nature of the Heralds and their divine duties, an attribute the Bondsmiths alone could address.
