The woods south of Sevenarches. This is where the real arches are located, making it sacred to the Oakstewards.
Strange things have been happening in the Wildwood. There were temagyr (fey creatures that are the embodiment of the fear of being hunted in the dark) and we ran into a strange area that had occult and fey magic opening and closing little portals. We find an altar with corrupt druids trying to sacrifice a unicorn in the heart of it as well, followers of Bolan.
