The session begins with the party returning to the Burnt Bridge Tavern to confront their original client. Mickle utilizes his Broom of Flying to eavesdrop on the room from outside, hearing the conspirators discuss rigging fights and accusing the party of being in league with the thieves.

Before a plan can be formed, Amnon sneaks into the building through a window to confront the men in the hallway. A brief struggle ensues, followed by the deafening report of a blunderbuss. By the time the party enters, they find Amnon dead and his body ransacked. A quick investigation of the corpse recovers his Pearl of Power, Ring of Truth, and Headband of Intellect, though his other magical items have been stolen.

The tavern proprietor calls for the guards, and five members of the Black Guard—the city’s elite, law enforcers—arrive. After a Zone of Truth spell confirms the party’s innocence, the guards cordon off the area and allow them to leave. However, Mickle, attempting to pickpocket a guard while invisible/gaseous, is caught and blasted with a necrotic spell. He takes 31 necrotic damage, which reduces his maximum hit points until a long rest.

Back at the Sloop Dogg, the party meets Draven, a bald man with severe burn scars who has been hired by Georgie Hristo to assist the party in hunting the Neolithid.

The next morning, the party hires a private investigator, Vitaly Stepan, to locate their missing crewmen, Ormus and Gil. While at Vitaly's office, Blu smokes a potent drug called Ogre's Breath, which grants him a +4 bonus to Dexterity saving throws but carries the risk of swelling the brain and tongue.

The party enters the sewers via a manhole in the street. After descending a ladder that terminates in a 40-foot drop, they splash into two feet of filth. Using a Lion and a Mastiff from a Bag of Tricks as scouts, the party heads south toward sounds of activity.

Their progress is interrupted by a Glyph of Warding (Force damage) burned into a wall. While most of the party survives the blast, the Mastiff is killed instantly.

The party encounters a group of “sewer junkies” and a spellcaster in a makeshift antechamber.

• Drathus delivers a series of Smite-fueled strikes with his executioner’s axe, while Draven utilizes Scorching Ray.
• The enemy spellcaster nearly petrifies Draven with a stone-skin spell.
• Blu eliminates a talkative marksman with a precision rifle shot to the head.
• Grundel pummels the final crackhead into unconsciousness.

Following the combat, the party recovers a Junkie +1 Dagger, a +1 Glaive, and a Dancing Monkey Fruit. They also discover a mysterious Astrolabe Globe that contains a magical item sealed within a conjuration barrier. Interrogation of the surviving wizard reveals they are manufacturing a narcotic using Neolithid droppings.

The party moves deeper into the complex, turning a massive iron crank to lift a portcullis. They discover a fully operational Drug Lab manned by twelve technicians and guarded by two Cave Bears.

A secondary skirmish erupts:

• Draven casts Fireball, centered on the bears, which causes the lab equipment to explode in a chain reaction.
• The explosions kill both bears and several technicians, filling the room with chemical smoke.
• Drathus executes the final ruffian, while the remaining spellcaster surrenders.

The party identifies three primary drugs being produced in the lab:

• Sleepy Salt: Grants +5 Temp HP and bludgeoning resistance, but induces an hour of sleep.
• Spiral: A liquid that numbs pain (advantage on pain saves) but causes severe dizziness (disadvantage on Dex saves).
• Illithidust: Made from fermented Neolithid droppings. It provides random psionic powers (telepathy, mage hand, or psychic damage) but may cause long-term intelligence penalties.

The session ends with the captured “Stony Boy” pointing toward a final door, revealing the location of the Neolithid.
