The party initially tracked the cultists to see if they found “Her” but met only dead cultists and a dead mindflayer(?). Finding little of interest (besides the crates? in the one room) the party returned to take the mine carts.
The party split in two groups with Leaf Derdrin and Vice squeezing with the polar bear. The party zoomed down the track (sometimes going to fast and spilling out of their carts) and made it to a building that looked like a temple. The infernal temple was guarded by two devils and a number of duregar. Within the temple a devil was creating a portal to somewhere, but was killed by Derdrin before being able to do anything.
