From publisher blurb: TYRANTS OF THE PURPLE CITY is a location companion for Tier 2 gaming groups looking for urban adventures in Avernus. Plot hooks, quests, and NPCs await inside the walls of the Purple City! Parties sailing the Styx might encounter the infernal settlement known as Hogdrull, where they can bargain for power, treasure, or a definitive way out of the First Layer of Hell, interacting with the factions involved in the power game happening in this city. Will they stop before the web of espionage and treason gets them once and for all? Includes worldbuilding advice, plot hooks, a new city for Avernus, full of locations; and three Tier 2 quests; as well as new creatures and magic items.
