So with the whole notion of hazy memories of the ancient world still residing in the memories of some, besides potentially giving us a hint as to what the Twelve are (Hades's analogies to Nald'thal, ranging from the sign of Gemini, to his aspect of death and domain of sorcery have been noted), I think it also may be an answer as to why Sharlayan has some similarities with Amaurot, like its style of government, its focus on acquiring knowledge and reverence of it and its non-interventionist attitude, as well as the ancient Greek elements to its architecture. We know there was at least one Ascian active there (Emmerololth on Val), but I wonder if it ever piqued their interest and whether others have invested some time there. Even just being the origin point for many a Scion must intrigue some of them.
