Cj parker and Azriel sent the following report to TMN:

We took a detour in PC1 to get a few folks to the first PF-training book. As everyone was signed up and leaving the SW pit, Noivad asked Azriel if he could remind him where the path next to the book went to. Azriel jumped out of his boots, made sure he wasn't joking and immediately ran back to take a look. Amazingly, clear as day, there was a 2-sparkle path right next to PF Book 1!
Noivad and Azriel hopped through the path into another section of library, which contains a single book. It has the same sunstone image as "Book 4", but when we bumped it, we could not comprehend its lessons. The book is titled Tart'targ's Orbing Gates.
However, once everyone came back to look, the two Mystics along, Sylune and Org du Lac, were able to start training with this book, in the art of orbing gates, whatever those may turn out to be. With luck, this training will reveal a way further forward!
We have some theories upon this book's purpose, and we took Sylune up to the EP to get some experience, but we are still in the early days of our research, and the full purpose has yet to be known.
