Found another interesting excerpt:"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 progress, it was related to the very nature of the heralds and their divine duties, an attribute the Bondsmiths alone could address." The heralds where created by the shards no? So could them speaking to the shards not make sense in this application?
