Disasters and other campaign modding things

I have made a new campaign to muck around with... I've been changing some values here & there to see how it changes the game. So far no crashes.

Has anyone mucked around with the "descr_disasters" file? Does it actually fire any events? If so how? I just copied it from the "base folder" to my campaign. If any of yiz do know, has anyone seen the "horde" event?

Another question too, in M:TW there was a revolt setting per province. Is that adjustable in R:TW?

Cheers
