I decided to put my speculation on the shadowy monster in a new post.

Okay, well first it seems to be either and elder dragon, or a new monster type, seeing as the body style does not fit the style of the others. The wings are NOT attached to the front arms, something seen currently only in elder dragons.

And it looks like the wings may be feathery. And in the final shot, the one that has a picture in the gallery above, the legs have some spikes. There could also be some fur.

Lots of "Coulds" but the video is not clear.
