Thee Princyples of Arckane Sciences
A series of four books penned by one “Osiriani Nethys” that seem to outline the means by which magic can be scientifically analyzed, tested, experimented with, and thereby enhanced. Books of the first two volumes are considered somewhat hard to find, but the next two volumes are almost impossible to find by ordinary means.
A “Redrick Usher” stumbled upon a copy of the third addition quite by accident and under very extraordinary means while he was on a dreamscape (?) in Norgorbers Creepy House. He is currently keeping his copy hidden, so that he can divulge it to the party in small increments, thus insuring his own safety and security.
