This is taken from a loading screen in MotB, they did the same thing with OC, they mention Rashemen in a loading screen
"Evan as far north as Rashemen, sailors whisper of distant Chult, a land of steaming jungles, deadly disease, and massive reptilian monsters. Local peoples cling to coastal regions, mounting occasional expeditions into the deep jungle... and living in fear of serpents who can take the shape of men."
So next stop Chult ? ^^
