The open plains is a wide area of tall grass where it can stretch out for miles. there are barely any creatures around this area but if there is one seen, they are most likely going to be afraid of you then you will be afraid of them. There is a large stone pillar along a path threw the plains that talk about how this place was a battle scene where war had been started and finished in that one place, so you might stumble upon a few head stone's or find old pieces of weapons or armor in the tall grass.
