This was the
chant used by the
Shel'Nod natives, who were
indigenous to a rather small portion of the
nodescape, though it was
rumored there were many more inhabiting
mirror nodespace.
It was used only by their mystics, during their attempts to divine answers from the node gods. They would concentrate on a question, and then create a nodeshell for it. They would then chant this phrase over and over to the newly made nodeshell, and eventually the answer would come to them.
When the Euro-Noders invaded their land and killed them all (like they did with just about every other group in the nodescape), they fortunately did not just forget about these natives, and thus we know things like this today. In fact, young noders have been known to use this divining technique in fun.
