Editing Wisrtum:The Magic of Wisrtum (section)

==Arcane Magic==
Arcane magic is a powerful, yet fickle art, powered by manna that permeates the world; as it has done since the dawn of creation. The degree of manna saturation over extremely large areas is not completely uniform. Most areas are sufficiently saturated with manna to allow the sufficiently gifted to wield magic. At some points in the earth, powerful conduits of magic, called ley-lines, run producing increased manna saturation: where these lines intersect is produces even more heavily saturated manna zones. Though exceedingly rare, legends record a few instances of extremely powerful magical exchanges which temporarily reduced the amount of ambient manna in a given area. In some places, manna is strongly conducive to the casting of some spells, and not others. Perhaps the most infamous and perplexing of which, the Narmer desert region. In defiance of the understanding of even the most learned of sages, Narmer strongly favors the casting of death-magic and makes the casting of curative spells difficult at best for both mage and cleric alike. In addition, some areas are void of manna, making the casting of arcane magic a complete impossibility.
