Miasma Stream
From Final Fantasy Wiki
The Miasma Stream is a barrier which hinders travel between regions of the Final Fantasy Crystal Chronicles continent. Caravans without a Chalice or a Chalice imbued with the wrong element suffer drastically in a Miasma Stream. Moogles like Stiltzkin seems unaffected by them, however. Miasma Streams can be found separating Tipa Peninsula, Ironmine Downs, the Vale of Alfritaria, Veo Lu, the Plains of Fum, the Rebena Plains, and the Abyss.
