Insanity Questions

[Chaafii]

Please forgive the newbie question, but where does insanity come from? Is it a spell or just from being in enemy domain? If the latter, is it an issue with every race? I've only observed it when I butt heads with R'lyeh. Then again, I've only played a few games.

LA R'leyh's dominion spreads insanity.

IF there are other ways to get it, they're very rare.

A couple of unique items makes one go insane, too.

Thanks very much. Me thinks I won't play against R'lyeh again anytime soon.

Yow, I just noticed this too as half my elite minotaurs started whaling on each other.

Any advice to deal with such a problem? Is there any cure to insanity? Are holy units more resistant to it?

Thanks

Preach and spread dominion before invading. Temples are really, really important
