#elemental border

just as the Farlands are an imperfect border plane for the material planes, so the elemental planes are for each other. travelling normally, an elemental plane will largely be rendered just like a material plane. but, because the elemental planes are so intricately woven around each other, their borders are just as imperfect as the Farlands. so, border elemental planes are where one plane is essentially stuck to or crossing through another.
