Anyone gotten a Lagufaeth raid on Tikawara?

[Zap Gun For Hire]

So I was poking about some of the game data files in regards to Tikawara, and I eventually noticed some references to a raid of Lagufaeth on the village, presumably either to try to free their captive hatchlings or some sort of revenge.

 

But I can't figure out how to trigger it.  I played around a bit with some game situations, but couldn't get it to occur.  So I thought I'd ask folks here if they've ever seen this raid happen in their games, and if they remember how it happened.

 

And if folks haven't, now we have something new to try to get to happen.
