Tempest

The four-armed emperor who conquered the skies of Marr'd. It is said he sailed with his fleet of Dragonwing-Sailed Ships into the stars, seeking new worlds to conquer, but some say he met his fate on the shores of Phobos. His Citadel still hides in the skies.

Kai learned the story of Tempest when he was very young. For a year, he cried whenever Phobos crested the horizon.
