On the rimward sector map included on page 76 of (the PDF edtion of) ISP3, there is a single entry covering the location of the Alexandrian Covenant.
Does this entry refer solely to the world of Pharos (the estranged capital of a now-sundered realm); or do the other remaining worlds of what had once been a (relatively) unified state lie within the same area? Or the now-dead worlds of Cyrene and Sophos, for that matter?
(To put it another way, were the systems of the Covenant grouped together akin to the occupied worlds in places like the Chaine, Hyades, or Pleiades Clusters; or are the other surviving worlds of the Covenant more widely spread, but are simply not shown on the sector map?)
