Inside Connection

(Races of Destiny, page 153, DnD 3.5)

[General]

Choose a specific organization, such as a town's militia, a particular church, a guild, or one of the illumian cabals (see Chapter 3). You have strong personal connections within that organization, as well as insight into its membership.

Benefit

You gain a +4 circumstance bonus on Bluff, Diplomacy, Gather Information, Knowledge (local), and Sense Motive checks made in conjunction with that organization.

Special

You can gain this feat multiple times. Its effects do not stack. Each time you take this feat, it applies to a new organization. The DM should limit characters to selecting only those organizations with which they have a positive or neutral relationship. For instance, a character might not be allowed to select an enemy organization, or one whose existence and/or operations aren't well known to him.
