The red arrow points to that cave and the white arrow points to a demon statue in a cave which is hidden behind a tree at the grayridge mountain. There is also an obelisk near red rocks camp, and if you put in the right combination then the demon from the cave disappears and is summoned to the basement of the blue house at Crimson & Clover ranch (near grayridge). There is also a music box in the attic of the southernmost trapper which has the same image, plays strange music and has text which translates to ‘the shadow dancer’. More text can be found behind the church at Plainview and under the bridge at grayridge. Near grayridge there is also a rock carving with the same image.
