A One-Round High-Level Living City Tournament
From the introduction:
It seems that you only just returned from your last assignment when you receive Lord Blacktree's message to report to his tent. Ever since descending into this foul place you have been among those who have born the brunt of the worst that the underdark could throw at you. Drow beyond number, cave ins, deep dragons, liches and other nightmarish undead, beholders, puddings, slimes, fire giants and the list goes on.
