Demons in Cullen Bog?Follow

Hi all,

I've seen a bunch of big-*** demonlike creatures in the Bog of Cullen. They appeared to have wings and moving like in and out of a stony-crag-center, like a circular motion. The bog fascinates me, so I came back for a couple of screenshots but I could't refind them. Anyone seen these and/or taken screenshots?
