Approach the Sisters. Doubtless the Sororitas know of what has happened by now, from your adoring guard if nothing else. It would be best to speak with them soon, before they can form their own opinion of these events in total isolation.
Worth noting,
As much as the navy represents a vague threat of possible orbital bombardment, maybe, if they're clued in enough to know what's going on, the Sisters are probably the biggest personal and political threat to Ignatius.
Like, when some priest starts making power grabs and preaching hetorodox teachings, and maybe glowing with 'the Emperor's holy light' (read: manifested abilities as a latent Psyker channelled through a lifetime immersed in the Imperial Creed, and/or may already be a Daemonhost), it's the Sisters who gear up and put a stop to that shit before it snowballs into another Goge Vandire. This is their
job. We've impressed the one Sister who's been at our side, yes, but the rest? Left to their own devices, it is entirely likely they'll default to their usual modus operandi as the Ecclesiarchy's housekeeping service. Remember: just because your church and/or flock seem clean is no reason not to give them a good scrub-down with cleansing fire.
It can always be more on fire.
They're also uh... not pushovers. They're the heavy hitters of the Imperium's domestic paramilitary forces, the folks you call in when even the army of Judge Dredd knockoffs with homing shotguns and tanks can't handle a situation. We're a Solar, yes - we're also barely out of chargen, and should not expect to socially steamroller people for whom stomping on demagogue psykers and hidden daemonhosts and nested cults with supernaturally persuasive rhetoric is their stock in trade, nor should we expect our office to insulate us very much - the Sororitas are deeply enmeshed in the doctrinal politics of the Ecclesiarchy, and often act as the hatchet women of the clergy. 100%, they
will have protocols for what to do if a Cardinal or similarly highly ranked figure goes rogue or becomes corrupted but is still outwardly pious and loyal enough that simply offing them is considered politically unwise.
So, yeah, probably a good idea to have a sit-down with them early and try to get them on side. Note that means on side not just with us, personally, but also our approach to rule - the Sisters of Battle are like, Black Templar level devoted to their ethos of "PRAY, KILL, BURN, PRAY, KILL, BURN!" and even if we can earn their loyalty we are
absolutely going to have to worry about them cracking open the economy-size barrels of promethium for anybody who displays insufficient devotion to our word, plus everybody within a ten meter radius of same.
