You might not be able to spot the Hero of Hyrule in Dying Light, but you can find his legendary sword. During the story mission that takes you from the Slums to Old Town, you'll arrive at a staging areas where survivors make the trek one by one. If you happen to have done Dawud's side quest to get him a gun, you'll find him and his son waiting to cross to Old Town. His son, as it happens, is carrying a toy version of the Master Sword! Sadly, he doesn't seem willing to part with it.
