Breath of the Wild
Atun Valley is a low elevation area where the main pathway connects from the Floria Bridge out east to Lurelin Village. At the far east of the valley, just before the entrance to Lurelin Village, the Yah Rin Shrine can be found on the north side of the pathway.
At the northwest part of the valley, there is a very tall Bokoblin base with numerous Red Bokoblin, Blue Bokoblin, and Black Bokoblin. A wooden treasure chest can be found a the top of the base containing a Soldier's Bow.
A Blue Bokoblin can be found along the pathway, near a broken down wagon. He is chasing down Regan, a local resident from Lurelin Village.
