>>5261203>The Ostracized / Write In (Xana II)I could be wrong and the Ostracized is not Xana II, but if it is my reasonings why this would be a good first stop:
-If we can gain its true allegiance, we can gain some legitimacy and credit. Xana II was notoriously defiant of Mars but was seen as a wonder and a mystery enough to attract the eye of the Emperor. It could even gain us credit with the Emperor by bringing it into proper compliance instead of a more autonomous ally as in OTL
-It's perhaps one of the farthest flung forges in the Galaxy, bordering the Halo Stars. If we do gain its allegiance, this is the perfect place to set up our Pariah Project. It will be out of the way of the astronomican, so a Shadow in the Warp will be no problem. In fact, we could easily hide it because its lonely star has no other places for habitation, making it an ideal hidey hole for our own secrets
-Making it a Null Planet will potentially neutralize its risk of joining Chaos later in the Heresy and also ward away some of the Halo Star madness, maybe.
-What the fuck is a giant forge world that rivals mars doing in the middle of nowhere? Could have some sort of giant drive engine! They did supposedly move it into the eye of terror in the Heresy
Importantly
we cannot expect every forge world to fall to Talos Persuasion either, not even Lorgar or the Emperor were that charismatic. If every human world just smiled and agreed to compliance, they wouldn't need the Legion. We may want to actually practice militarily subjugating or coercing a forge world, because there will and have been in canon forge worlds that did not simply bow before the Mechanicum. So at some point we should practice bringing a forge world into compliance. Xana II being far away with few diplomatic ties and being seen as a prize is ideal for this
We may, or in fact, will at some point have to fight fellow Mechanicum and learn how as well as how to reconcile after compliance is obntained. We will earn credit for bringing Xana into compliance where no other couldit's far away in a dark corner of space, the perfect spot to claim and make our hidden box no one else is allowed in. If we can win over the locals. By charisma or force. And we have the force.
