Where does the party go next?
The party is fully healed (except for Xaod). Belaver and Lylamwyn are essentially out of spells. If the party wants to rest, you would have the option of resting in a room, resting in the wilderness outside the Mines complex, or resting back at the Orc infested hamlet of Rastor.
Kerwyn invisibly scouts around.
Kerwyn scouts north of the room where the party thinks the Trog priest lived and finds a Y intersection. At the Y intersection, two Troglydyte guards are posted. Kerwyn sneaks past the guards. He passes through five or six caves occupied by a half dozen Troglydytes . The Trogs appear wary, but Kerwyn does not see anyone preparing a counter-attack. Kerwyn stops scouting and returns to the party after reaching a cave that is occupied by a winged lion with a spiky tail.
Kerwyn scouts south in the direction that Maridosen fled.
Kerwyn passes through a storage room and enters a room that appears to once have been used for some sort of mining process. Two rows of long wooden troughs, collapsing from rot in places extend the length of this long chamber. At the far eastern end, a dark shaft plunges downward. A thick flexible tube made of hides is connected to a large set of bellows and then drops down into a shaft. The other end of the tube rests limply on the ground near the eastern edge of the troughs. Kerwyn finds a torn and worm-eaten book that might be interesting to Lylamwyn.
Kerwyn enters the next room and finds a massive, dust covered rusty machine of some sort. A chute leads into a pair of massive stone cylinders and a wooden trough underneath. The cylinders appear to be connected by gears to a single, huge crank, sized for a giant to turn. Small bits of stone lie scattered around the machine.
The next chamber that Kerwyn enters is large and mostly empty. Three four-wheeled ore carts are here, with high sides and a strange sort of handle on one end. One of the carts lies on its side. To the south, two rough hewn passages lead out the room, a pair of iron rails running down the middle of both, with lengths of timber supporting the rails at set intervals.
Kerwyn thinks that the whole party could ride in one of the carts to wherever the rails go. And that the incline would make a ride fun. And that treasure, prisoners, etc. could also be transported by cart.
