Our heroes began investigating their fallen enemies. Kallius identified the leader’s enchanted chain and falchion, but was unsuccessful in figuring out the stone around his necks. The others only had personal effects, and each carried a foul-smelling bag of rich loam and fungus.
Meanwhile, Boomah was scouting down the mining passages while his magical enhancements lasted. He found several side tunnels and obviously inhabited areas, but came across no enemies.
After his invisibility faded and he lowed back to normal speed, he checked out the last passage. Creeping silently down the passage, he stumbled onto a large subterranean lizard which had also been hiding in the darkness. He fled back to the group, with the lizard snapping at his heels.
Kallius rushed up to face the monster, and Boomah sprinted past to safety. Saerin and Luix followed in, with the freshly blooded Dremahl supporting them. The lizard dropped from the wall it was clinging to and lashed out at the enemies surrounding it. When the magus struck with a vicious blow, it let out a howling scream that was answered from further down the passage. Three small lizards rushed out of the shadows and sunk their tiny teeth into the elf.
The trio maintained focus of the largest enemy and it soon fell under their combined attacks. When she she dropped, the small lizards panicked and fled. The group chose not to follow and returned to the entry hall.
There was a wooden partition over the western cavern with a door set into it. Saerin and Boomah teamed up to pick the lock, and they soon found themselves in a looted store room stinking of trog and death. They found some dry goods, mining gear and a primitively constructed cage. Inside they discovered the corpse of a crippled human, who had been there for a couple days.
They quickly moved on to the other side, and defeated that lock as well. The partition wall had been often been pulled back before, and there were gouges in the rough stone from its movement. Inside, they found stabling for the riding lizards but no actual beasts.
They left it behind and returned to the passage that held the fiery draconic leader. They heard nothing, and sent the alchemist and ranger ahead to scout. They came upon a Y-passage, but the rails only continued on the left. Following up, they soon found a large machine mounted atop the end of a long, straight rail. It smelled of salamander breath and had venting tube up to the roof of the passage. Kallius determined that the machine was designed to build up pressure and release it in a powerful blast.
Following the straight rail, they moved up the passage, disregarding smaller side tunnels on the left. The rail ended in a ragged crack in the tunnel wall— and a crater into darkness. As our heroes discussed what to do next, they started hearing quiet scraping and muffled movement. Fearing a mass assault from creatures in the side tunnels — they retreated to a tunnel on the far side of the passage to wait.
