Lore community, help me out: what do other nations do when Bilgewater is invaded by the Black Mist?
I recently posted a joke thread about it being silly for Bilgewater to send a fleet of ships to shoot cannons at a bunch of ghost-fog. A more serious discussion started in the comments, with one key topic being what other the other nations of Valoran are doing while Bilgewater's getting flooded year after year by the Mist.
Ideas ranged from "they are helping, but it's not much use" to "they don't care about Bilgewater" to "they're getting invaded themselves and can't spare the manpower".

I can add a little context here.
Like everything else on the Shadow Isles, the Black Mist was at one point a lot less black (it might not have even been a mist, though no one's old enough to remember). With the corruption of the Islands it transformed into the Black Mist, which is now a kind of traversal mechanism for the growing number of ghosts/spirits/creatures that inhabit SI. They can 'hitch a ride' on the mists, as it were, and travel inside them to populated areas brimming with unharrowed souls - souls which the things that inhabit SI are preternaturally drawn to. The mist only comes off the island during The Harrowing, though no one yet knows why.
The Mists are a local problem, but they're a growing local problem - every year the mists get bigger as more and more people/things are consumed and integrated by the Isles. Like Graves said in that bookend piece, the mists are likely powerful enough to travel anywhere at this point, not just the closest most populated region (Bilgewater for you cartography fans). That means far-flung population centers like Demacia, Piltover, and even Shurima are all potentially at risk. And while concentrated drives against the things lurking around in the mists can kinda-sorta repel the stuff (thus decreasing the spread and therefore the risk), it only staves off the threat for so long.
So in conclusion, no, it's not a military invasion. It's more like an El Niño... full of skeletons.
Skel Niño.
While enlightening as to what exactly the Mist is, I'm still not really sure what other Valoranian nations do this time every year. If it's just a local problem, and the Mist contains a lot of quite killable skeletons and zombies and such, why isn't someone sending aid? Bilgewater's a major mercantile center; even setting aside altruism and compassion, many states would have a vested interest in helping them out. At the very least, you'd think you could count on Demacia to be all heroic and come charging in, and Noxus has an established privateering relationship with Bilgewater, so it seems they'd also have a stake in this.
So. Ideas? How do you imagine the other nations of Runeterra reacting to the Mist?
