Stark 01: Screencap 02
A closer look at the map, showing some of the riverlands, and even a bit of the Iron Islands with Ten Towers. Most notably, I think, is the Twins—does this give a hint of how the castle will seem when we see it late in the series?
Of course, as noted in comments, there seems to be an error (that, or a name change): House Reed‘s Greywater Watch has been rendered as Greytower Watch.
