Didn't guilliman have some xenos tech that could light up a planet like the astronomicon? i've not read anything in the HH series past the unremembered empire, so maybe i've missed its destruction or something. if not then that could be directed at terra, and give guidance to ships instead or astr.

If the Emperor died though, i think that the Imperium would shatter, as every psyker would notice if the astronomicon went down, and you just cant shut up that many people. humanities collective spirit would be crushed and then all kinds of shit will hit the fan. So the Primarch that returns first will (if the emperor died before his return) find the imperium even less organised than it is at the moment, and probably needs to start a new empire somewhere, and start the Great Crusade v.2
