{This is an excerpt from Black Ninja Handbook, by the Dark Lords.}
The Nine Maxims of the Ninja are the central guiding principles of the Black Ninja. Study them well and live by them.
Strengthen the body; it is your foundation.
Stay in the shadows and be silent.
Endure all hardships; overcome all adversity.
Control your mind; discipline your desires.
Affiliate with a Clan and obey its rules.
Think outside all boxes.
Be mindful of your surroundings.
Make war by way of deception.
Be like the wind—a formless, invisible force.
