This seems like a pretty good Castille start? Not ironman, sadly, but I've not availed myself of any takebacksies.
It's 1550. I've got eight colonial nations, an heir on the throne of Denmark (ft. Sweden), Naples and Savoy under PU, and my vassals are Tlemcen
Map kind of cuts off but I or Tlemcen have everything up to the edge of the Mamluks.
