Clearly http://uesp.net/wiki/Skyrim:Fall_of_the_Space_Core,_Vol_1 isn't intended by Bethesda to be taken as canon in any sense of the word, but since when has that ever been fun? So, what do y'all make of these little rascals? Offshoot of the Magne Ge who elected to drift through Oblivion rather than return to Aetherius? Constructs of Jyggalag designed to scout the Void in preparation for a hostile takeover? Illicit spectra? The Amaranth?
