Bran is on a journey. It's all a bit Fellowship of the Ring. The landscape is described. Eagles fly overhead: that's probably not good. We get to hear a story from a long time ago about places that have not been mentioned before. Green Men may make future appearances.
They meet a Liddle who offers them shelter and a cave and tells them news of the wider world. Bran vows to be nice to Liddles if he ever gets the chance.
