The heroes must break the siege on Tiamat’s last stronghold—the City of Brass. With no time to spare, they must sneak into the city, find a way to throw open the gates, and allow Bahamut’s force inside before another army arrives to crush the forces of good. All that lies between the heroes and success is Tiamat’s blue exarch and the labyrinthine ways of the City’s efreet-run society. A Scales of War adventure for 27th-level characters.
