A player of the spanish forum says that when the OL raze an island with this plot, it does not count for the total of 5 cities that he must raze to win. I think that it is considered a city, so if I raze Cerridor Sea and Shrouded Gulf (islands as cities), and Orris and Gafford it is obvious that the OL has razed a total of 4 cities and he gains 1+4 CT each week.
I think that this plot has clear rules, but he thinks that I am wrong... What do you think?
