Casting A 10th Level Spell

10th level spells have a magnitude of power which is leaps and bounds ahead of 9th level spells. Who cares about dropping a few meteors when you can change the face of the planet itself. The difference is similar to the difference between walking somewhere, or teleporting there directly. As such these spells have been shunned away by the gods, as one can only imagine what someone with evil intent would do with such powers. There is a legend that somewhere in a forgotten crypt, a parchment containing the information necessary to casting and dispelling 10th level spell is hidden. Hidden by the gods themselves for they lacked the power to destroy it.
