I feel the Eulmore blurb matters somewhat.

With its influence extending across the majority of the isle of Kholusia, this powerful military nation once stood firm against the onslaught of the sin eaters. Recent years have seen a drastic shift in Eulmore's position, with the wealthy upper classes turning their backs on the plight of the world, indulging in an endless parade of decadence and debauchery.
I feel like them suddenly ceasing their fight, the island suffering few sin eater attacks, a massive refugee population built around the city proper because of that, and a giant wall that would keep that population penned in are likely connected. There's also the fact that Minfilia, who successfully halted the Flood's advance in Ahm Arang, ended up trapped in caverns beneath the city.
