On my second playthrough of Valhalla and noticed something new (maybe!)...
When you go to the eagle jump with Hytham, I took a short cut. As you go up the hill you can climb the rocks on the left to the top, and there are some iron ore sources. However, there is also a weird glyph... I haven't seen any other post on it but I am pretty sure I am not the only person to have seen it. Does anyone know what it is and are there others throughout the world?
