The prince of a secret village of ninjas at the north pole
they fled there after being chased from japan by there acient foe the pirates...

the first generation of ninjas to reach the north pole when totaly blind... which only made them more kick ass.
(much like a pirate becomes more kick as if you cut of his hand and replace it with a hook).

the ninja prince will be more detailed then the random normal ninjas of which one will only see eyes and weapons.

(lazy ass strategy ^_^)
