Hraefn
Swooping high and low, you mentally map the area, spying the small stream that bisects most of the valley. Though thin and winding, it appears clear enough as the grasses do much to filter any toxins that might be washing out of the hills. The metal caves are another story, looking as if it is a giant tower of some kind that, over the eons, was absorbed by the Oerth and converted into a mountain itself. What the shape is under the ground, however, is impossible to tell.
Closer inspection of the two cave mouths, however, reveal that they are not caves at all. Or, at the least, Hraefn notes that there is no opening where the metal entrances are. Its as if they are blocked by some form of metal valve.
