The Princesses of Zahard are a team of elite female warriors chosen to serve Jahad. They generally come from the 10 Great Families, and are extremely powerful, often ruling over their own floors. Jahad gives them his own blood, further enhancing their combat skills. Princesses are forbidden from marrying or having children, to prevent Jahad's power from being spread too much.
Being in the 10 Great Families alone is not enough to make a Princess, they must all pass through rigourous training and defeat numerous competitors to earn the position.
