During the travel, Avan maintains the Pass Without Trace spell whenever it finishes, and attempts to predict the next two days of weather (Take 10 = 22) checking whether it's necessary to use the Endure Elements scrolls when it gets extreme.
At the canyon, Avan is not entirely sure about this plan, but has a backup if everything goes badly. He uses Speak with Animals to instruct Mr. Fluffles to stay 50 feet behind Ildrahil and not to fight when the ambush breaks out. He himself stays in the wagon for cover, with bow ready.
"I suggest we remain on or near the most direct route through this place. There's no telling where their settlement is, but we can bet they'll have eyes on the most likely paths for travelers. We find those eyes, and they can lead us to their home, whether unwittingly or through… persuasion. Any objections or alternate ideas?"
Albrecht nods in agreement to Bastion's plan, and resumes his place scouting for ambushers. Krama continues to march with the wagon, protecting it to the best of her ability.
Out of Character: I presume travelling along the ridges is impossible due to the fractured nature of the terrain?
In Character: Avan continues to scan the sheer cliff faces for any traces of movement. Fluffles keeps a keen eye out and sniffs at the ground and air every so often, trying to catch a scent.
"We should be getting close."
Bastion will suggest checking caves first for activity, then for signs of heavy traffic. A well used cave with no immediate signs of life might not be their settlement, but could easily be an outpost or storage.
