Johanna didn't seem terribly interested in backing down. "The ratfolk certainly can't hold the complex by themselves, there's hardly enough of them. Even though we broke the backs of the worst gangs here, new ones might rise, and just take over where the Lords of Rust left off. What if there's something worse down there? It's far safer to destroy the whole thing, and leave it buried. Even if it is valuable, it's also shown that it's incredibly dangerous."
