Like BW we have those ruins in BW2, but when we finish the main story-line, we can find in undella town a plasma sage and he will give us ghetis notebook which translate us the text in the ruins from ancient language to japanese and when we go to the 4th floor we can notice some black points in the text instead of the 3, 4, 5 and 6(the king) symbols in BW1, if someone understand japanese, please translte us to english
