A guild was an organization composed of like-minded individuals to further and protect their interests. Guilds appeared in many different forms but typically offered benefits such as camaraderie and even financial support to members. Large, powerful guilds could even control an aspect of a city, such as trade in certain goods. Guild membership was generally open to those who possessed some skill in the guild's primary activity. In many cases, interested persons needed only to approach the guild and apply for membership. You can only join up to 3 Guilds at any one time, not withstanding Adventurer's Guild.
