Re: wanted: diceand cubes from Carolus Magnus
Little cubes look to be about 9 1/2 (just under 10 mm); but I don't think the size matters for the game play.
Unfortunately the game is missing two whole colors: 40 blue and 40 yellow cubes. But I figure those must be for sale many places?
Regarding the missing special dice: If I can't replace them I think I can make due by appropriating the two dice from Masons and one from Ghost Stories. The Masons dice have the exact same colors on five of the faces (pink, blue, yellow, red, green) and I can use the sixth face ("?") to mean Castle. For the third die, I can borrow a Ghost Stories die and use red=red, blue=blue, green=green, white=pink and black=castle.
