What political, spiritual, and economic impact would losing Scintilla have on the Calixis Sector?
If something were to suddenly happen to Scintilla causing it to be separated indefinitely from the rest of the Calixis Sector (no communication to or from and no travel in or out), what would become of the Calixis Sector? With the sudden loss of the presiding sector government, the heads of the various Adepta (such as the Arbites, Administratum, Astra Telepathica, and the Ecclisiarchy) it would most definitely cause some major ripples.
I get the feeling that this could strain or even doom several planets due to lost tieth and other reports that were being tallied on Scintilla before sent for storage in the Proll system. Likewise, since the greatest bulk of weapons in the Calixis sector seems to also come from Scintilla, there could be some kind of backlash there as well. I feel that the nobles of Malfi would definitely seize this opportunity to take control of the Calixis sector (even if it's under the pretense of guiding it along the proper path until either communication can one again be established with Scintilla) but would they have any opposition?
What else could / might / would happen if Scintilla suddenly vanished?
