New Affiliations
To match the three organizations given to us in the Tome of Magic, I provide you with three additional affiliations.

Reclaimers of the Mind
Symbol: The symbol of the reclaimers is a brain, wrapped in bandages.
Background, Goals, and Dreams: The reclaimers are group of shadow magic users, psionicists, and diviners, all dedicated to the reclaiming of knowledge, lead at all times by a council of three dark minds.
Members: The reclaimers welcome all races equally, but only allow the magically or psionically adept enter their group. One is free to leave at any time, so long as they submit to having their mind probed for any withheld information.
Secrets: The ultimate goal of the reclaimers, beyond the mere accumulation of lore, is to pull Teka back into the material plane, possibly restoring his sanity while keeping his divinity intact. Hidden by the council is a portal leading to the plane of shadow, which they expect will be instrumental. Until a member finds a means to complete their ends, however, the reclaimers are happy to accumulate knowledge.
Type: College (secretly Cabal)
Scale: 2 (neighborhoods)

21-29                        Reclaimer: You can read a single piece of parchment as a full-round action. In addition, you may read items that were recently destroyed (reclaiming the raw knowledge from the destroyed item), as long as they were destroyed less than 1 round/level prior.

Shadowgauntlet
Symbol: the symbol of the shadowgauntlet is an emaciated hand with fingers that seem a bit too long (anyone familiar with shadowgaunts recognizes the hand as belonging to them).
Background, Goals, and Dreams: The shadowgauntlet, as it is named by others, exists entirely on the material plane, near the ruins of Gengardon. It appears, at first glance, to be an organization composed completely of shadowgaunts. When someone else enters though, they are treated as one of the group. Several sages, fighters, and explorers have traveled to the shadowgauntlet to meet the enigmatic shadowgaunts on equal grounds, where they can compete, fight, or trade equipment and information. Most people theorize that the shadowgauntlet is the shadowgaunt’s way of reaching out to other races. Despite the seeming fluidity of roles in the shadowgauntlet, senior members do seem to have more of a say in what happens, and members tend to offer wears to senior members with less compensation than normal.
Members: The shadowgauntlet is mostly comprised of Shadowgaunts, although anyone who enters the structure that holds it is heralded as, at the very least, a probationary member.
Type: Fighting Company
Scale: 2 (one structure plus planar visitors)

Code:

from senior members.
Titles, Benefits, and Duties: As a member of the Shadowgauntlet attends regularly over time, fights other members, brings in new stories, and fulfills the mission requests of others, they find themselves more respected amongst the other members of the shadowgauntlet. At the same time, some of the shadowy energies from the plane permeate the shadowgauntlet’s members due to their long proximity to it. The only thing that is truly expected from members is their regular participation, both in attendance and in missions.

Executive Powers: None.

The Seven Paths
Symbol: The symbol of the Seven Paths is seven equidistant lines stretching out from one source.
Background, Goals, and Dreams: The seven paths was founded by Farsen Gorlock, a half-orc initiate of the seven enigmas. Unusually philosophical for a half-orc, Farsen (the only Walker of Seven in the affiliation), he created the Seven Paths as a wizard college of sorts made exclusively for shadowcasters. Although the college is filled with shadowcaster students, only those that stay after their formal education to learn more actually enter the affiliation.
Members: Although there are no racial stigmas within the seven paths, shadowcasters alone are allowed to join.
Type: College
Scale: 5 (City)
