Well,I just got some possible info on the skull.Whatever it is,it possibly has something to do with the vortex in the water on this scan in the top right http://blog-imgs-60.fc2.com/m/h/3/mh3gf/20130516174028ea1.jpg because,in the description of the Frozen Sea it was possibly hinting to the vortex being made and used by some type of giant monster living in the water.
