Phantom Thief

The Thief Clan possesses a martial art known as the Ninefold Ghost Shadow Steps. Once mastered, it makes one's movement skills peerless beneath the heavens. But the price is destroying one's own dantian. The resulting frailty and poor health mean the practitioner is destined to have no part in martial arts. Even so, people of the martial world hail them as... chivalrous thieves!
