So, speaking frankly about this in a way I want to get to more organically as we go, like, Grace is obviously Bronze Faction. (Shocking, I know, given that the topic is called A Vision in Bronze). That is, she is aligned with the largest part of the Sidereal Host, who have been engaging in the political project of shoring up and supporting the Realm for its entire history. The why of that has a few complicated reasons -- for Grace personally, though, the biggest one is just that she was born in the Realm.R egardless, though, like, what is Grace's job? The Factional stuff is just like, the way that they think is best to carry that out. Let's go back to fundamentals
As a Sidereal, she helps to ensure that the destinies foreseen in the Loom of Fate and planned by the Bureau of Destiny come up pass, because doing so reinforces the fabric of reality, and falling to do so makes things get fucky and chaotic. It is also her job to safeguard the integrity of Creation. There are other things, but those are the most relevant ones. As a Joybringer in particular, the Division of Serenity is responsible for planning out relationships that matter to destiny -- certain romances, marriages, the happiness or lack of happiness of particular people, friendships etc. We can assume that heaven has any number of destinies planned that intersect with Bittern, people who live in or visit Bittern, people in the surrounding Blessed Isle or in the West who travel to or trade with Bittern or who will just be affected by its violent destruction. This is before we even consider what House Peleps does next, which will probably be fucking unhinged in its own right.
These two sailors are supposed to fall in love. This particular patrician man is supposed to have his heart broken and become a great poet. The marriage of these two regular fucking people from Bittern's working class districts is supposed to produce a child who will grow up and one day be one of the greatest mortal glass blowers in the Realm. A petty official is meant to not find happiness in their wonton corruption, and eventually to retire and find a different life. Destiny does not care about literally every single thing that happens to everyone, but there are specific moments and people who are very impactful to specific destinies.
When a powerful Exalt or group of Exalts decides to, say, unilaterally destroy a major city and murder hundreds of thousands of lives, all that is cast into chaos, all these destinies are fucked up, will never be realised, these people die when they're not supposed to, a nexus of fucking terror and human misery spreads out from there, affecting the plans of all five Bureau of Destiny Divisions, to say nothing of most other heavenly bureaus in some way. As has been mentioned, a shadowland probably opens -- a hole torn into the fabric of Creation, where it now merges with the Underworld, and probably a really bad one. The Immaculate Order as well as Heaven will have a bitch of a time stopping that from solidifying and getting it to close again.
Sometimes, unfortunately, a city is simply destined to be destroyed. It's foreseen in the Loom, there's no way to avoid it, or its survival is associated with worse outcomes. There's no version of events where everyone gets to be happy and prosperous. That is not the case with Bittern, and it is no part of Grace's job to just let people with a particular axe to grind against the Realm do this.
