People are being idiots. Would it kill them, would it damn them to Abaddon, to wait for one or two weeks until Sevar gets back from her punishment, to make any changes to this perfectly good status quo?
Unfortunately, as Maillol knows all too well, if you are not literally at the Worldwound then there are limits to how useful it can be to try to clamp down on friction between your subordinates. If you let dominance challenges resolve themselves, your subordinates resolve themselves into a stable low-tension arrangement where everyone knows who's stronger and the stronger ones are in charge. Anything you do to influence affairs away from that creates a higher-tension arrangement which you, as superior, will have to do ongoing work to maintain.
Maillol can foresee Sevar not being incredibly happy with this unfortunate bit of project manager wisdom, or feeling fully answered by the observation that they are supposed to be less heretical Asmodeans henceforth. But if Sevar didn't want this to happen the moment she stepped out, she should have spend more than three rounds on trying to prepare for it in advance, frankly.
