I returned to Canach's pub to find Sayida, and I filled her in on the Inquest facility and the presence of Overseer Kuda and this principal biomancer, Sebb. I was still unclear as to who was in charge of the Inquest, but we agreed the only way to get more information was to try following their trail through the caverns.
After activity calmed at the facility, I returned and followed the procurement team's circuitous path through the cavern system, eventually leading me north into Twisting Hollows—freebooter territory.
Outside a private bar called the Wardroom, I overheard a snippet of conversation—Agent Thessa speaking to a freebooter. I wasn't getting past the bouncer into the Wardroom without a password and a disguise. Luckily, I was able to get both off the nearby freebooters and gain access.
Inside the Wardroom, Agent Thessa was in deep negotiations with a freebooter representative called Seamus the Slick (likely a self-given nickname since his negotiation skills didn't seem to warrant it—he seemed mostly interested in acquiring barrels of "swill."). The Inquest agreed to provide the freebooters with weapons and golems, so long as the freebooters agreed to use them against the Hullgardeners—and keep the Tyrian Alliance busy in the process. The Inquest also provided supplies in exchange for freebooter intel and manpower somewhere inland.
I couldn't allow the freebooters to use those weapons and golems—they were too dangerous, and they'd tie up even more of our forces protecting Hullgarden. Before following the Inquest's trail north, I made my way back into Inquest territory and tracked down a set of codes that allowed me to turn off the freebooters' newly acquired golems' combat systems.
After sabotaging what supplies, weapons, and golems I could, Sayida checked in over comms. With the immediate threat to Hullgarden dealt with, I let her know I was ready to continue tracking the Inquest north.
