EDIT: forums went crazy and told me something about pidgeons and then I got two posts for the price of one! Ignore this one

Just out of curiosity, why exactly do the iconians have +100 espionage? Previously I assumed the were some kind of evil mindflayers, but recently I discovered they actually are a good civilization with no kind of minflayering mentioned at all. So.. err.. what's up with that?
While we're at it, why is there no espionage bonus for the Drath? With their shapeshifting and all. Not that I want them to be good at espionage (I play with the Drath a lot and couldn't care less about it), but I'm just curious.
By the way, I don't know much about GalCiv lore at all, so maybe it all makes sense somehow.
