The Thieves Guild is a secretive organization that brings together skilled criminals, primarily focused on theft and other illicit activities. Members often share resources, information, and protection, allowing them to operate more effectively in the shadows of society. They may have their own rules and codes of conduct, ensuring loyalty among members while punishing betrayal harshly. In many fantasy settings, such as in video games or literature, the Thieves Guild plays a crucial role in the underworld. Characters like rogues or assassins often seek membership to gain access to valuable contacts and training, enhancing their abilities to navigate the dangerous world of crime.
