You go with Dresk to the location he has found, behind a market in Khyber's Gate amongst piles of trash. It looks like an ant mount with a massive hole at the top, 7 feet across. You secure a rope and Dusty climbs down, carrying the rope with him. It's an easy climb with the sides of the holes have plenty of handholds. It's fairly solid but feels organic, moist and warm. From below an acrid smell rises. The hole decends 40ft before opening up into a large chamber where Dusty pauses. In the chamber are goblins, ogres and a basilisk on guard. But it is pitch black down here and although all inhabitants have darkvision Dusty is able to stay hidden from view. The hole decends further, into another chamber below and then further as far as Dusty can see. The inhabitants are chatting with each other about: a) how bored they are b) how unfair it is that they have to be down here while everyone else is having all the fun c) how much it stinks down here. Sylviel climbs down after Dusty and casts an illusory wall in front of them to hide them better. Sylviel readies herself to throw an eldritch blast at the Basilisk if they are discovered. Luckily because as Norm climbs down behind them his hand slips on the rope and he plummets. He catches himself partway down the rope but slams against the wall, alerting the guards. Sylviel throws eldritch blasts at the basilisk, killing it before it gets a chance to act. Ashana and Dresk climb down and join the battle which is completed fairly quickly. Norm recogises one of the Ogres as a Daask enforcer. You explore further into the chamber and find not much of interest, but Dusty and Norm are ambushed by peircers that fall from the ceiling in a subchamber.  You use another rope and climb down another 40 feet into the next chamber, in the same order as before. The chamber goes off two ways, to the left is some sort of storage area and the passage to the right is filled with webs. Dusty moves into the storage chamber where he sees guards carrying crates and barrels around. He sees a familiar face also doing the same. It is Sundry, the gnomish fence that he met once before. Sundry yells at Dusty to leave, but starts shooting a hand crossbow as he does so. The guards also move into attack. The battle is on, but the noise seems to attract attention from the webs and from the other side giant spiders emerge, also attacking. This battle ends up being very close, especially as the guards and Sundry are mere vessels for the cockroaches that inhabit them. As the hosts take fatal injuries the giant cockroaches emerge, ripping their hosts apart to attack you all. You are able to kill the roaches, but as you do so they explode in a shower of acid, burning and hurting you. You are badly hurt, so you take some time to rest. Searching the chamber as you do so and finding some useful items. You use a rope from the supplies to climb down to the bottom of a hole where a rouch rock stairway bends away to the south. You climb down these ancient and worn stairs, avoiding tripwires and find yourself in a passage with many alcoves, nooks and crannies. Norm finds a pile of green glowing eggs in the first nook and pokes them with his dagger. The egg pops, the force of the pop causing other eggs in the alcove to pop and larvae are thrown out. They let out a high pitched squeal as they emerge which seems to be a signal as nearly a dozen ill-formed cockroaches climb out of other nooks and crannies up the passageway. The larvae start crawling towards Norm as the cockroachs move in to attack.
