This place is far less secure than we were led to believe. The dredge move ever closer, and we need all available help to push them back. They're also sitting on a gold mine of dwarven artifacts, preventing us from studying them. On top of that, we've learned of a mysterious new threat, some sort of steam creatures. We've been trying to learn all we can about them, but we're at a loss. If they're truly dangerous, we need to know as soon as possible.
