While continuing thier journy along the road they are joined from behind by a gnome riding a troll. It is Trogdur and his new friend Smog. He explained that his new friend has amnisia and has no idea who he is.
As the group follows the road along a curve they emerge into a clearing in full view of a fortified roadside checkpoint. It was originally created to house soldiers while they patrol the roads but are told that recently a tiumverate arrived with new orders to question any groups traveling with non humans to see if they have committed any crimes and judge them. Gilby notices that some of the parts of the armor the soldiers are wearing don't match the rest. It appears that the newer pieces are black in color and have an irredescent sheen to it.
A guard notices the dead body wrapped up in the back of the cart and they expaine that they are on a quest and shows their papers to the guards. One of them walks off and returns in a few minutes to move them to the front of the line of people waiting to be questioned and shown in right away. along the way, one of the guards offers 100gp each for the dead elfs ears but are rebuffed by the party. The leader of the tiumverate questions them in a circle of truth about any crimes of which non were found. Then expaines that they are in need of assistance.
They had identified a group of dwarfs as spys and assassins and were holding them to send to Dechtera for questioning when they manages to dig into a cave system below the checkpoint. They send the party to reteave the dwarfs from the caves offering 50gp for each dwarf nose recovered and 100gp each if they are returned alive.
Because of the large size of their new Troll (dragonborn) companion they ask for help from the soldiers in digging out the dwarfs hole so they can all get to the caves. The cave ended at a hole in a metal plate that looks to have rusted through. They then find themselves in an underground metal tunnel which they can only summise was left over from the time before the apocolipse that ended the old world. The tunnel is caved in in one direction so they travel through the tunnel fo about a quarter mile when it opens into a stairwell going down and an open cabinet that was rummaged through which contained old tools. It looks like the dwarfs are now armed.
The bottom of the stairway opened into a hallway the led to some sort of old control room with crumbling rusted terminals alog the walls and one that was obviously made from better materials in the center of the room. Nothig functioned anymore and as they looked around was attacked by small acid creatures that were hiding in the rubble but among the junk they found some spools of gold thread (wire) which looked valuable. In the back was another stair that went to the remains of a living area where they fought some adult and juvenile borrowers. Obviously the dwarfs did not come this way so they returned to the first hallway and found another metal tunnal the led to a large circular room the went up and down into darkness.
It looked like the room once had walkways around the edges but only some of them were left. They could hear the dwarfs working somewhere above them and realised thy would have to climb the pipes on the far wall to get to the upper levels. While claiming the pipes the dwarfs started throwing stones at them and the fight began. Level to level they fought up the walkways, ladders and pipes. One by one the dwarfs lost their footing and so did the heroes of our group. Each falling into the darkness below with a loud splash followed by silence until there was only Smog and one charmed dwarf left. Not really knowing what to do Smog pushed the warf off the walkway and did a swan dive after him as that was where everyone else had went.
It turned out the the bottom of the underground silo was in a fast moving underground river and as they fell into it they were wisked away by the current underwater, smashing into the sides as they went until eventually they were thrown into a blinding light, and fell into a pool under where water was emerging from the side of a cliff. Some were unconscious and others fighting to get to shore. In the end all but one of the Dwarfs were captured and nobody died. However, one dwarf (Dexter) had escaped and spent and exaused the bound dwarfs were marched all night to get back to checkpoint justice. The Group was paid and allowed to sleem in the barex beds to recover. The Cleric of the triumvirate also cast gentle repose on siltani's body.
