You have stumbled into the final level of the tower, which stretches high
into the clouds.  A dragon created from the purest crystal sleeps here, its
frosty breath freezing the magically levitated cloud it sleeps on.  Inside
its body, suspended in time lies a brighly shining key surrounded by a pile
of gold.  There is a doorway upwards which almost didn't catch your
attention because it as well is in the shape of a cloud.
A beautiful dragon made of the purest crystal greets you.
