Quick search on the Wiki reveles that that basicly means Caerwyn vs. pretty much everyone else. Thulsoma and Averoth don't seems to exist properly anymore and Madina is having some sort of civil war now? Whereas Sanguis Astroism seems to be expanding with pretty much no internal problems. That be an accurate summary?
Not "everyone else", no. A good chunk of the North, however, but even that means incredible travel distances. South of that, Sanguis Astroism is very small. It is small in Asylon and Terran, and is almost (or completely) meaningless everywhere else (Barca, D'Hara, Madina, Aurvandil, Grand Duchy of Fissoa, Luria Nova, and Pian en Luries).
Them not killing each other too much in the North doesn't make them quite united either, though, if when the war with Caerwyn ends (regardless of the result), I'd have a hard time seeing them able to do anything other than turn on each other, due to how far everyone else is.
