The story of how the black arrow that killed Smaug came to Bard. 'Black Arrow!" said the bowman. "Black arrow! I have saved you to the last. You have never failed me and always I have recovered you. I had you from my father and he from of old. If ever you came from the forges of the true King under the Mountain, go now and speed well!"

The story of how the Black Arrow came to be in Bard’s hands, and how Legolas got his tattoo.
