The Heroes (Now only Eydan, Gracehana, and Irok) go down the tunnels from the glassworks and into a side cavern. They encounter a sinspawn, who seems particularly interested in Irok, and in fact poisons him.
After defeating the guard, they see a paladin with the emerald brooch. She explains that she was sent to investigate a strange aura coming from beneath the earth. She split up with her party and had used her ability to detect evil to arrive here. She offers to go investigate further with them.
The cavern ends when it comes to a room inside of a catacomb, with the tunnel breaking straight into the side of it. In the next room, they find a red statue of a woman with draconian features. Her hair is tied back with blades and she has in her hands a book with seven pointed star and a Metal-and-Ivory Ransuer. Irok takes the masterwork polearm.
Then down the steps to a room with a large round pool in the center. There, they battle a Vargouille who paralyzes Irok in an attempt to turn him into one of it’s own.
They find a spiral staircase leading up to the surface – the original entrance. They back track and find a prison room with two sinspawn lying in wait. They are defeated quickly, again seeming to focus on Irok, and on Torissa as well this time. Going further they find a torture room and a study.
Then a strange room used for housing zombies in pits, guarded by a Draconian. They defeat the Draconian, and the zombies with little difficultly. To the south, they find a spiral staircase leading down, from which disturbing moans, screams, and groans can be heard. They also find the lounge which is enchanted with a levitation spell.
The final room contains the Quasit demon mentioned in Tsuto’s Journal. The tiny figure holds a dead Tsuto and drops him into a glowing triangular orange pool. It glows brightly and a sinspawn emerges. Then she cuts her wrist, letting the blood drip into the pool, and another sinspawn appears. The pools dims considerably, but does not go out completely.
The quasit attempts to use her invisibility and ability to summon monsters to defeat the party. In the end, Irok leaps from the stairs and deals a mortal blow with the Masterwork Ransuer, ending the battle.
