From the Introduction:
Welcome to Dues for the Dead, a D&D Expeditions adventure, part of the official D&D Adventurers League organized play system and the Tyranny of Dragons storyline season.
This adventure is designed for three to seven 1st-4th level characters, and is optimized for five 2nd level characters. Characters outside this level range cannot participate in this adventure. Players with ineligible characters can create a new 1st-level character or use a pregenerated character.
