Nation/Race Guide

[Aetius]

I have briefly scanned the newbie guide, but I was hoping to find a more consice source of data of the various races/nations. In particular I am interested in the hidden effects each race has, such as Ulm's incredible money generation. Happened to play a long hot-seat game with my brother-in-law over the Thanksgiving Holiday, was shocked at the amount of income that Ulm generates.

I am curious if the more experienced community members could state what some of the other hidden benefits are. In particular what does Marignon's Inquisition allow you to do and how does one take advantage of the extra defences created by T'ien C'hi with an increased order scale? I noticed in the hot-seat game as Marignon I never had the unrest problems as my brother-in-law's Ulmish. I know for a fact that he did not raise taxes.
