She charms the bar keeper and a few others, idly getting a better idea of what's doing on. The feud's not flared up enough to threaten them while they stay the night, and there is in fact a local mayor trying to broker peace who's been looking for trustworthy-seeming outsiders to help defray the situation a bit. Two Great people are more than they could've hoped for; the innkeeper's cautiously optimistic people would keep to whatever judgement at least for a while.
Ashes has a good bit of insight into local culture - they won't be able to magically fix things, and proper trials would take forever and haven't been going anywhere anyways given a lack of proof, but Ashes's suggestion that both groups help each other out "charitably" for damages each side's taken goes over decently enough.
They're able to keep moving the next day, and Ashes picks up the pace enough to make up for any time lost; she seems well rested, at least.
Being asked to sit in judgement seems pretty common, actually, though most arguments they're asked to hear are less tense (and one, a building war centered around a prince accused of murdering the other side's princess, is more tense; Ashes manages to prove to both sides that they're being played by a third, an arms dealer, convincing them to ally, and mentions off-handedly to Elesse having once fought both groups in separate battles, long ago, though they clearly don't recognize her). Ashes tells stories about the peoples and landmarks they pass as they go.
There's a few tombs that've surged that they end up called on to fight, too - more than is typical, apparently, enough so that Ashes is quietly concerned. Several are powerful enough to actually seriously challenge them, too - one big enough that when they get to their destination the local King is willing to give them several concessions if they'll deal with it, as all of his loyal knights and even Great mercenaries who have drifted through have failed.
They're able to clear it out without significant injury. Ashes shows off more than she has before - she's an immensely talented fighter, and clearly enjoys the fights.
And then Ashes lays the tomb to rest as she has all the others, staggering as she finishes.
