As part of the Pathfinder Society's attempts to make allies across all nations, a few Pathfinders have made contact with a low-ranking Blood Lord among the leadership of the undead nation of Geb, the lich Msasa Kuatuz. As part of her attempts to climb the ranks, she's agreed to introduce the Society's representatives to her fellow Blood Lords, so long as the Society is willing to assist her with one little problem: she hasn't seen her ghoul friend in a number of years and she'd like the Society to check on them. Once inside the ghoul academic's home, the Pathfinders find evidence of giant bugs, assassination attempts, and scholarly disarray, but where could the ghoul be?
