Something Is Wrong
The Shadow Trails valley was wider than Rui expected, and also not as dark as the name suggested. It had been several hours since they entered the valley. For some reason Rui pictured a super narrow path perpetually bathed in darkness when he heard the name 'Shadow Trails'.
However, this was not a good thing, ultimately. The valley being very wide allowed for a much larger area over which the bandits could base and hide in. Especially since the valley was covered in a dense forest, yet the there was enough space for bandits to maneuver comfortably. Furthermore, the ground inclined upwards up both sides of the travelling convoy, giving the bandits huge stealth and surveillance advantage.
