I have never seen "The horde is attacking" either, but it's a limited duration event, so, unless you spend alot of time between defeating moder and defeating yagluth, you should not see it.

That's why I wonder why people build earthen barrier so much. The only non-limited duration event that can do anything to a plain stone wall is trolls, and those are easily defeated, or you can just run around repairing the walls for a few minutes if you're worried about it.

That's wolves and fulings do bust through stone walls. I've had an attack in a mountain fort and they got through a few blocks. It's a bit of a pain.
