A final shot of Harrenhal, which introduces a purple banner belonging to… who? Not sure what house, if any, this represents, and is probably a made-up set of arms for some reason. There are no houses in the west (in George’s notes, at least) that have a purple field. The closest I can think of is if they took the Brax arms of a purple unicorn on silver, and reversed the colors. Which is not utterly impossible, but it seems unlikely.
The Westeros network consists of several different sites, including a forum and a wiki, for all your A Song of Ice and Fire needs.
