If I were writing Infernals, I'd make clear that while the ultimate goal is to free the Yozi, it's possible that that is impossible, and even if it is possible, it will likely take a long time to come to fruition. The more immediate goals of the Yozi are to increase the power of the Unquestionables, and to impose their will on Creation through their Exalted. This allows storytellers to run 'the Yozi are breaking free' plots, but limits the Reclamation to 'a bunch of Infernals are taking over Nexus/Destroying Gem/Whatever.'
Yeah, if you look at Kerisgame, the real ultimate goal of the "Reclamation" is the Third Circles wanting to be able to give orders to Exalts so they have assets who can go further their plans, summon them into Creation, and generally allow beings who are as powerful as the most powerful gods reign to play on Creation as players for the first time since the PW.
... this still means that there are... well, if you say there's an average 15 3rd Circles per Yozi, that means that there are 120 demon princes [1] who are giving orders to 50 GSPs and trying to squabble over who gets their orders done first. Which is why in An Teng, three Infernals are having to handle getting orders from five demon princes and of them, three of the demon princes each want unchallenged, unquestioned dominion over the principalities.
The moral of this story is that the Third Circles are finding that there aren't enough Green Sun Princes and that the ones who got in first and who managed to get patronage of them early have a massive advantage. And that the demand for GSP services is so high that they're having to bid more to acquire their services in the bidding wars in the All-Thing, quite apart from the backdoor system of patronage which they're also using. Quite a few cabals are already forming, where Third Circles with interests in common are setting up block votes and favour trading to ensure GSP orders are set for mutual benefit [2].
And Ligier is playing the system by being patron to lots and lots of GSPs and so is hogging them, because he's both a charismatic handsome bastard and he's also incredibly rich and loaded down with things that the GSPs want. Witness how he acquired Keris as a client, by being the one who can repair and convert the Royal Yacht of An Teng into Keris' flagship. The fact that he can teach GSNF expansions is just an added bonus.
[1] Kerisgame has Metagaos, Kimbery, Malfeas, Adorjan, TED, Cecelyne, SWLIHN and Isidoros all onboard.
[2] Some of them are considering whether they can start treating the new Solars like they do the GSPs, because humans love Hell-crack and demon hookers, right? And if they can't get their hands on a GSP who'll take orders, coaxing a Solar into their service might be even better.
