[Excerpt from Kazau’s backstory]: Nishimura Kazau (to use a more proper ordering of his name) belonged to a ninja clan in the capital city of the great nation of Mizushima. When the rest of his clan was killed by a rival clan, Kazau did the only thing he could think to do to ensure his survival: he sought help from a powerful noble his clan had once crossed. Being pragmatic, the noble agreed to secretly move Kazau out of the country and to a recently discovered island on the condition that Kazau find out as much as he could about the political cliamate and other goings-on of that island. Kazau agreed and was smuggled to Aoteroa where he now steals items of great value and occasionally fences them. True to his word, he sends bi-weekly updates to his sponsor in Mizushima. Some small percentage of what he writes is actually true.
Kazau’s exploits on Aoteroa have made him wealthy enough that he need no longer practice his art as a master theif — so now he just does it for fun. When Councilman Oronar and The Unusuals put together a team to reclaim Erconhelm and thwart the Cult of Setesh, Kazau was hired. It is said that he remained a member of The Unusuals and is now the leader of that clan, though his whereabouts have been particularly difficult to determine.
