The term "Open Lord" refers to a title used in the fictional setting of the Forgotten Realms, a popular campaign setting for the Dungeons & Dragons role-playing game. The Open Lord is the leader of the city of Waterdeep, known for its diverse population and rich history. This position is often held by a prominent figure who is responsible for overseeing the city's governance and representing its interests. Unlike other lords, the Open Lord's identity is typically public knowledge, promoting transparency in leadership. The role is often associated with political intrigue, as the Open Lord must navigate the complex relationships among the city's various factions, including the Lords of Waterdeep and the Harper organization.
