I noticed the banner for the Pirate 101 Twitter page has been changed. First, its amazing if you have not seen it yet you should check it out. Second, its concept art that is currently not in the game. The closest area I have seen is a house you can purchase in the Crown shop. Although similar it's not the same area.
Could this be concept art for an upcoming world/area or just a really cool picture? It looks very Darkmore if you ask me, which would be amazing if that's one of the upcoming worlds .
