Whirlwind is an air dragon with unicorn ancestry - two species that could not be more opposite in nature, which made her never quite fit in with either group.  Other dragons were envious of her beauty, while unicorns shunned her for her ability to fly.  But Whirlwind found peace within the dark and stormy clouds, where she learned to harness the tempest power within her.  Despite her turbulent youth, she was the first to defend both dragons and unicorns when the trolls began hunting them, unleashing her ferocity in a brilliant and powerful rainbow that could be seen throughout many regions of Skylands.  From that day forward, evil-doers would quake when dark clouds brewed, and run from the rainbow that followed the storm.
