Forum:Tears of Ragnos

I found a referrence to the Tears of Ragnos, a saber crystal of very deep. deep purple hue that can be found at the Valley of the Jedi on Wikipedia. I'm assuming it's not canon since Marka Ragnos and the Valley of the Jedi have virtually nothing to do with each other and I can't find information on it here or anywhere else other than its obscure mention. At this point, I just want to know where the hell it came from.
