You're one of a small group of copaxis who have earned the right to call yourself an inheritor of Gadrath, a powerful order of mystics and solarians that once called Gadrathar Fortress their home. With the help of its sapient robot guardians, you've rekindled in yourself a small amount of copaxis' ancient connection to copi during a pilgrimage to the ancient rotating citadel in the sky above Tabrid Minor's southern pole, allowing you to exert a small amount of control on the gravitational forces acting on your body. As long as you're conscious, you take no falling damage, regardless of the distance you fall.
