If you miss the next gate, you keep falling until it comes around again.
For some reason, even lighter-than-air things fall in Fall, just the same. Terminal velocity and wind conditions on Fall are survivable for most or all air-breathers. Things dropped mid-fall, however, are liable to be lost.
Fall has no discernible background magic or magic-capability.
Fall is more of a bridge or gateway and, because of its nature, is unlikely to be much use in the Twine Wars.
