Maltacus has created a small modification that alters the unit and agent cards/icons
in the Beginning of the End Times submod for Call of Warhammer (for Medieval II: Total War - Kingdoms).
So far this mod covers the Skaven, Tomb Kings, Ogres and Dwarfs.
Almost all content is also compatible with the unaltered Call of Warhammer mod, and the mod is save-game compatible.
