Guards along the Western walls saw a cavalry man ride out from main gate towards the hoard. They say he was getting close to the enemy defenses when he unfurled a large white flag or banner. No one could make out his livery but the rider must have been from one of the great houses to be able to leave through the gate. The rider was reportedly ripped to shreds by a pack of worgs after a giant rock flew out of the darkness and dropped the rider from his horse.
