What is a ninja? Everywhere you turn, you find a different definitation. Is the ninja a cruel supernatural assassin with godlike powers of invisibility, illusion, and teleportation? A modern, feeling Oriental man or woman with family, job responsibilities, and an interesting double life? A stone-faced westerner who miraculously inherits the duties of an Ancient ninja clan tradition when his or her brother or sister is slain? A martial arts practitioner celebrating hundreds of years of unbroken tradition?

The ninja is a highly trained spy who is expert in matters of intrusion, sabotage, and elimination. He or she, is a part of a tight-knit clan whose profession and goals he or she shares. Some ninja are generalists, equally at home in matters of stealth and combat. Some are specialists, becoming adept at social skills, magic or interaction with nature.

They're all exotic, secretive, and dangerous.
