Whatever you like to refer to the formation as whether it's, earthmote, floating island, or skyland/skisland...this one is a chunk of earth floating high above ground level. It spirals upward clockwise unit it reaches a bridge that leads up to the center mass. The center mass floats above the rest of the formation and contains a stone portal foundation.
This is a great map for those encounters where you want your party to battle their way upward to stop a creature from entering or leaving the plane through a special portal. Perhaps the party needs to make use of this ancient magical site, but it is guarded by fierce flying monstrosities.
