From Introduction: Welcome to the Fantasy Netbook Community Council Netbook of Classes. This Netbook has been published as a community effort to increase the pool of classes, both core and prestige, available to player characters. This Netbook was designed in support of the D20 System environment. As with any community project, there are several ideas, alternate rules, variants, classes, etc., that would never be approved or sanctioned by the official design team. This entire book is considered optional. You must seek your game master’s approval before using any classes presented here.
