That done, the Jarl and his housecarls lead the party to the only mine entrance still unblocked (stopping at the infravision statue to get all the humans some night sight on the way). The entrance was right next to the elevator the party had been using, so they has to pass through the minotaur lair to get there. Which they were able to do without incident thanks to the two Vrilya who accompanied the Jarl. Once in the mine tunnels, the Jarl took his leave of the party and returned to his halls. The party, forming a marching order and hefting weapons, headed out. After just a few steps, the walls around them started to fade away. The next thing everyone knew, they were waking up in a large mined out chamber. Most notably, all their equipment and supplies were gone, and they were dressed just in old rags and equip with mining tools and lanterns. They were also not alone. A half dozen skeletons, equip much like themselves, approached. The party prepared to do battle, and Riley began to call on the power of Habuu to drive away the undead fiends. Only to realize he had no holy symbol with which to channel the wrath of his god. And was unable to see in the dark anyway, as his infravision lens were likewise gone. So all raised shovels and picks and dealt with them the old fashioned way; smashing them. But these skeletons were tougher than normal, with bones encrusted in mineral deposits. One of the skeletons killed a sheep, and Darnorth vaulted over the other wooly creature to aid his embattled comrades. Lacking their usual armor and weapons, the skeletons hurt the party badly before the last one fell.
So back down the tunnels they marched, heading west out of the gold-chamber this time. They immediately entered another open area, this one occupied by another group of skeletons. These undead were picking up rocks and placing them in a trio of mining carts, a task they stopped at once when the party appeared. Several picked up tools and prepared to attack, while the rest of the skeletons grabbed a mine cart and rolled it down the slope towards the intruders. The cart slammed into Darnorth, throwing him to the ground. Rather than risk a knock down fight in their under-equip state, Bjorn cast a web spell to trap the ore carts and as many of the undead as possible. The rest were taken down by mining tools and thrown rocks.
Burning away the web that now blocked their progress west, they headed out again and once more broke into a mined out chamber. This one contained a small alter carved out of stone. Riley, wracking his brain to remember his clerical training, identified it as a shrine to Lughrin, the old god of miners. And behind it hung a silver warhammer, which the cleric recalled was the holy symbol of the mining god. Darnorth snatched the weapon from it's hook, while Kern examined the altar for traps. He found no traps, but did notice what appeared to be a hollow or hole under the stone. Gurruk bent down and started digging it out, and uncovered a trove containing flasks of holy water, 3 potions of extra healing, and a clerical scroll (bless, resist cold x3, continual light, striking x2). This fortunate find was shared among the group, and then Darnorth and hammer led them once more to the west.
