Renegades from the Wu Tang temple in Northern China. They perfected the Wu Tang sword style and then left the temple to run thier own clan. History sometimes says that they are murderous people but there are two sides to every story and sometimes history doesn't capture both sides.
The Wu Tang Clan were what is described above, not to be confused with a rap music group that adopted thier name. In America you can pay enough money and just about copyright any word or phrase in my opinion.
