@Spluff: It would depend on exactly which galaxy you want, but many real-world dwarf satellite galaxies are sufficiently small so as to be, in practice, individual sectors that are spatially separated from the rest of their galaxy. As such, they should be no more problematic than introducing a new sector to Endless Space.

@Tybusen: As Wormy says, there are ways of hiding galaxies. Telescopes won't help you see the current status of galaxies unless you're within a few light decades of them, at which point you're already there, and post-Annihilation madness could easily obscure hyperspatial sensing. Even with Groxkiller's idea, the discovery of extant galaxies might not be particularly shocking even if the reason for their existence is unprecedented.

One thing I'd like to point out is that there are several Annihilated galaxies that could be brought back well. Although I do think it would be better to work on these galaxies that we are already in canon, introducing entirely new galaxies is of course an option. We could even have nearby ones: galaxies that would go on this map are Circinus and the M94 Group; equally close but off the bottom-left of the map is the Sculptor Group.
 * In the M81 Group (Nexus Cluster), Bode's Galaxy was described as colonised by the Vartekians; the nearby Cigar Galaxy, although never mentioned in fiction, is a suitable candidate for one of their other galaxies that were never named. Vartekian presence may have been removed during the (mostly unwritten) Vartekian War, so either of these galaxies could be the site of post-Vartekian fiction.
 * Also in the Nexus Cluster, Noiisqa and Siiralore only have very short pages, each being colonised by a single Milky Way nation. Most of the Astral Cluster has very little written about it; the Aurora and Nimbus Galaxies don't even have their own pages.
 * Wormy's written a bit about the Black Eye Galaxy but, besides the presence of Conqrix and a DCP campaign against them, we know very little about it.
