A Two-Round Living Greyhawk Core Adventure
From the introduction:
Old Wicked is on the verge of success, and the forces of good are desperately looking for ways to stop him. When Tenser hears of knowledge hidden on the Abyss, he suspects a trap, but he cannot ignore any chance at victory, however slim it might be - and Iuz is not without enemies in that place. So now he is looking for adventurers, hoping that they have an easier time of remaining undetected in that dismal place than he would have. Are you willing to go in his stead?
A 2-round Core adventure set in the Abyss for character levels 9 to 15.
Part four of "Ascension".
