Riding along the way from Edoras toward Marton was normally not so awful. Of course, she was usually aiming to bypass Marton, in case her welcome would have expired with Leoffrith's nominal exile, but this time she was planning to stop in on her way to Fréasburg.
What most made it awful was the fact that she couldn't really see Marton. Then, she started seeing scavengers. All sorts: four-legged, two-legged, winged, and some mounted. That and some traces of smoke from buildings that hadn't burnt out completely yet. This was a much more recent bit of devastation than what she'd encountered earlier at Langhold, and thus much more dangerous. Many of these scavengers were probably just the stragglers of the raid, still busy looting. And she was a big target. Well, mounted on one, at least.
