I have an old copy of Time of Tumult that has the original writeup of the Locust Crusade. That chapter, of course, is crammed full of stuff, because it provides writeups for Alchemicals, talks about Autochthonia, and describes the Locust Crusade itself.
I dimly recall another book -- possibly a first edition book -- that provided alternative Locust Crusades. The chronicle that I'm running right now is set primarily in the North and I am considering introducing the Locust Crusade as a plotline in the North. However, I am exceedingly lazy, and if someone else has already done the legwork for me on this, I am inclined to steal it.
From reviewing the previews of the PDFs of the 2nd edition Alchemicals and Autochthonia books, it looks like the info I'm looking for isn't in there. But I'm not positive.
Can anybody point me in the right direction?
