Not to worry, because meanwhile the pseudo-Egyptian robotic Necrons have launched an assault on the Blood Ravens' flank, keeping them off your back. Say you get distracted from attacking the Blood Ravens because the mech-loving weebs called Tau are too attractive a target. Right from the off you've got two hostile neighbours to deal with-but so does everyone else. Of The War With Chile receive a plain text, but a fully-formatted piece. Each has a single mobile army, led by their commander, who can attack an adjacent territory. This adventure short story introduced us to Falmer and Thone who are orchid. There are seven factions competing for the planet Kronus, which makes it a pretty crowded place.
The proof of that is Dark Crusade, which ditched Dawn of War's prior narrative style (complete with in-game Space Marines trying to emote by flapping their lantern jaws and stiffly performing emotes), and instead created a more freeform campaign structure. I love a cheesy RTS cutscene, whether it involves actors hamming it up or in-game models blown up to a scale they should never have been seen at, but even I have to admit they're optional.
