The Paper Airship is a discovery related to the Lands Of Ice.
Nobody knows how this piece of paper survived the trials of ages. Perhaps it is a mystery that will never be solved. Some say that inscribed upon the paper is a map to a fabled land, but nobody knows the truth.
It will circle below the upper cloud layers near the Southern Cross, flying in a counter-clockwise path around the ends of the Lands of Ice. This means that if you fly a clockwise path around the Lands of Ice, you will easily encounter it.
