This is a mod for CoW 1.31 (and it is in Russian) that adds the faction of Brettonia to Call of Warhammer created by Red Falcon from the "СiЧъ Total WarS" forums
I took the liberty of downloading and rehosting the sub-mod for everybody on the TWC to enjoy.
LINK: Rise of Brettonia
Again, this sub-mod is currently for CoW 1.31. I am planning on converting it to 1.44 after my testing is done.
