Breath of the Wild
The Elma Knolls is located just north of Hyrule Castle. The area is a steady incline to the top of the hill. It is a rather grassy hill with trees sporadically found throughout. There is a wide variety of materials and animals found in the area, with the only threat being a Forest Octorok, as well as some Stalmoblins at nighttime.
