You'll discover the 'Village Overlook' base camp here. Create a rope bridge and slide down, then hide behind the fence. Wait for the third guard to move away entirely, then dispatch the two remaining guards with headshots.
All collectibles upper Mountain Village area, part 1.
There's some [SALVAGE] near the arch you used to slide down, and some more [SALVAGE] inside the building. [RELIC - #2 - KANPO HERBS (MEDICINAL HERB VIAL)] is also inside, lying on a desk.
: You'll most likely find [BOW PARTS 2/2] if you've been collecting salvage according to this guide.
Head upstairs and light [ILLUMINATION STATUE #3]. Slide down the rope and search underneath the hut to find a [GPS CACHE]. If you enter the hut and leap across the platform to the north you can light [ILLUMINATION STATUE #4] here, and also make a rope bridge to the tree trunk in the platform near the waterfall. No need to cross it; this just makes backtracking easier. Climb the roof of the hut, light the torch and pull it away from the [SALVAGE BAG] to make it catch fire.
Create a rope bridge northeast of the hut to continue. Wait with climbing the last part of the rock wall until the two guards finish conversing and move into the tunnel to the left. Here you'll also find [ILLUMINATION STATUE #5]. You can dispatch the two guards in any way you like, it doesn't really matter. Create another rope bridge and you'll reach a platform with the entrance to an optional tomb.
