Harpers
Harpers are altruists who work behind the scenes to keep power out of the hands of evil tyrants. In the current situation, it doesn’t take long for them to suspect that the Zhentarim is wholly or partially responsible for the escalation of violence in Waterdeep. Harper spies might use the adventurers as instruments to get at the truth. Various nobles and guildmasters in the city are Harper sympathizers.
Harpers prefer to conduct their business in bustling inns and taverns such as the Yawning Portal, or in quiet locations such as the City of the Dead.
