A Thieves' Guild is an organized group of criminals who engage in theft and other illegal activities. These guilds often operate in secrecy and have their own rules, codes of conduct, and hierarchies. Members typically share resources, information, and skills to enhance their criminal endeavors, creating a sense of community among thieves. Historically, Thieves' Guilds have existed in various cultures, often providing protection and support for their members. They may also engage in activities like extortion or smuggling. In some fictional settings, such as fantasy literature and role-playing games, these guilds are depicted as powerful organizations with significant influence over local economies and politics.
