Whoops--in my previous message, "coo coup/fish & fowl," I used the word "eidolon" when I should have used "aquastor" (even though I think that they might be used interchangably by the commonality of the Commonwealth, for my own sense of mental cohesion I like to keep them separate: "eidolon" as beam-to-the-brain ghost, and "aquastor" as physically manifested ghost of hologrammic silvery dust).
The ghosts of Main Frame seem to be eidolons, by our man Sciathan's description and the experience of Silk's friends.
[Since "quaesitor" in early Roman times was a criminal investigator (mainly homicide, I think), I continue to wonder if "aquastors" are ghost detectives--that is, investigators of the living on behalf of the dead. Or there are the "quaestors," deputies of magistrates, that grew through the years of the Republic from a population of two to forty until Augustus reduced them to twenty: this job was the entry-level magistry sought by ambitious young men. In context of "aquastor" this suggests a hierarchy and government of the dead.]
