Please help this is really mind-boggling to me and I can't tell if it's just because I'm overthinking it or if it's actually confusing. If you take an island and 2 different civilizations, then put up a wall halfway through the island and place 1 civilization on one side and the other civilization on the other side, would that make the island 2 peninsulas, or is it still an island? would the whole land be an island and one side be a peninsula? ( see picture for better explanation )
