That isn't an Ascended Sleeper...I believe it's one of Hermaeus Mora's Seekers. These equally tentacled beings of his that seek and obtain the knowledge of the changing realms. History moves onward, Hermaeus Mora's endless library may be filled...but not with the most recent events!

That's just my thought. It isn't as hunched and ginormous as the sleepers I remember.
