Before there were Hej'sorai and Jen'saraii/Light Templars, there was... the Tumanji Order. The Tumanji Order is an order older than both the oldest orders, though no one has heard of it. They tried to use both the Lightside and Darkside in a balance, trying to get the upsides of both the Darkside and Lightside. Their colors are Purple/Grey, since the Hej'sorai were Red/Black and Jensaraii/Light Templars were Blue/White.
They found themselves sometimes on the side of Evil, though they were supposed to be the 'Good guys'.
