LOL - I was just tossing some ideas around for 5th edition Forgotten Realms. With the Dragonwall gone in 4e, I was thinking maybe a 'landrise' (huge cliff-face where the wall used to be, and everything east of the wall 'sank' by at least 100'. The red zone is the part I picture now being underwater. The point would be to move the China-like and Japanese-like cultures into Murghom and Semphar (a mass exodus), to bring them closer to the main campaign area. As I said, its just an idea I am toying with ATM.
