Is it? Does that mean ULTRA SPINE SALAD and TURBINE DOLPHIN are also valid?

There's no need for me to write any explanation for why Empire North and Empire South both get the college wizards, because pretty much any Empire army can use any of them. I won't be representing Patriarchs in the game, other than Balthasar Gelt, the Bright Wizard one (I forget the name - he was supreme patriarch before Gelt) and possibly Volans himself.

Just to be clear, by splitting Empire into two nations, I'm not writing in a civil war or representing the periods when the crown was challenged. It's merely a method of splitting up the huge unit list. I was planning on doing the same with Orcs and Goblins (which Okin is now doing I believe).

If you want to represent a civil war, that's up to you to roleplay just as if you want to represent a full and undivided Empire you'd have to make special rules allying the two nations, or combine them into one super nation.
