Mage of the Arcane Order

From DevroWiki

The Mage of the Arcane Order PrC is available to any mage or specialist registered and active within the Tribunal of Arcane Law. Entering into this prestige class denotes entry into the political echelon of the Tribunal, and those who rise through its rank becomes masters and regents within the Tribunal. Those who do not take levels in this prestige class have little political clout within the Tribunal, regardless of their level in either mage, sorcerer, or specialist classes.

This PrC is not considered open gaming content, and is available in Complete Arcane, pg. 48, from Wizards of the Coast.
