Warrior Spirit

A Warrior Spirit is a type of Celestial spirit that appears on earth to challenge certain Adepts to various forms of Duels. If the Adept wins, or at least fights with honor, the Warrior Spirit will pledge his friendship and at a latter date, normally when the Adept is in trouble, he will reappear to lend aid.
Warrior Spirits are particularly fond of the Military Orders. In fact, many of them appear to be members of the various Military Orders.
