I can give you all the information on the themes, but from what I can tell what exactly do you want?

I dont' quite get the national mages part, you want to put the highest possible of each type? Or the strongest mage/priest?

There are not really all that many units per race. Maybe you could just add the basic types and the special ones.

And maybe a little section with the name of what the Sacreds are.

I can compile a list together if you can use the information. I already have most of it from doing the Nation/Theme Strength/Weakness guide that is in progress.
