"My name is Reidak.  I'm a Piraka.  Does that mean anything to you?"
	"Onua frowned.  Piraka was a Matoran term, but one that was rarely used.   Loosely translated it meant "thief and murdered," and it was so vile a term that the Matoran considered it an obscenity.  The Toa of Earth couldn't imagine why someone would voluntarily brand himself a Piraka.
