I would like to add mine thoughts to this discussion, although I cannot claim to be of Golemian or Necrovian descent.
While I had never had opportunity to visit the Island of the Gateway myself, I had heard that there doth lie upon it an Aramor Assembler - such a landmark doth not exist upon the mainland.
To assemble an Aramor within this construct, one doth require many resources, and one who were able should then obtain an Aramor Fenth, that may create eight Aramors.
I would wonder what doth occur when one attempts to construct an Aramor, but without all the required resources. Perhaps, if one were to assemble one without a Fossil, or without a Crystal - the resulting Aramor mightst be formed, yet incomplete.
If I do recall, Golemus were an island that had many constructs, of many scientists. Mayhap, the Aramor had been one of them - one that had taken many iterations, until one had stumbled upon the correct recipe that were within the Assembler today. If such a scientist had attempted to construct an Aramor, but had not known how to do so, mayhap, an Empty Aramor might have become.
I do note that the Empty Aramors do wander Golemus, bound to none, while all other Aramors within the realm were bound to another being, as a creature of allegiance. Perhaps it were the absence of the soul that were bound - thus making one an Empty Aramor - that thus doth make these unable to be bound in the same way. Thus they mightst be fated to roam the island for eternity - as they cannot be sacrificed at an Altar.
Of the Shades, I cannot claim to have expertise. Yet, I believe that it may have been Khalazdad that had once studied them, and found them to have been formed of imbalance. Perhaps it were the eternal cycle of roaming of the Empty Aramors that doth bring about the eternal roaming of the Shades, within Necrovion - for the imbalance that were formed of an eternal being, never to return to naught, must bring with it another. In another realm, one mightst consider the presence of matter, and anti-matter, that were formed of one another. Mayhap, this were the Shade and the Empty Aramor - a soul without a vessel, and a vessel without a soul.
