Let me tell you the tale of a man obsessed with legacy. Oroku Saki, was a legendary monk who followed the path of enlightenment, but his ever increasing paranoia about his mortal life caused him to search out dark magics blurring the lines between undeath, and eternal life.
Now a dark reflection of his ultimate potential, this demonic warrior clad in razor sharp armor operates under his new moniker, The Shredder. Saki then formed a clan of monks to accumulate wealth, and keep the fear behind his name relevant, feeding the dark magics that fuel him. Having since faded into the shadows, mired in his depraved research, you should be aware of any involvement with his clan, or researching the legends associated with him. Drawing his attention could prove deadly.
