very lukewarm opinion but the riverlands probably has the most interesting & cool characters of any region in westeros. just such a wide scope of everything there. literally any distinct faction of audiences could find a batch of appealing riverlands characters. the more medievalist catholic or historical battle tactics people have the tullys & freys (also mallister/vance/piper), the strongs for the f&b crowd, a massively long list of significant ladies and knights, the whole blackwood-bracken feud, and just house blackwood in general, house darry and their targaryen loyalism, and then don’t forget the magic & mysticism! brynden rivers, the ghost of high heart, harrenhal, isle of faces/green men, mad danelle lothston as well as beric & lady stoneheart in the current story. not forgetting about jenny of oldstones either! there’s just so much developed story there that the other regions (even the north) don’t have as much of, to where the riverlands’ prominence is apparent to *any* kind of reader.
