DnDNerds!

New Party! While the dwarves who took Dragonfang Mountain recover, we meet the Caravan Crew: dwarven arcane brothers Obin the Fortress and Ibin the Scorcher, VS the shifter spore druid, Eero the goliath monk, and the return of ZaZa the goblin rogue, who once served a nixie for a year and has the gills to prove it. They're taking some mules loaded up with iron, steel, and leather from Llorkh up into the mountains in winter, delivering to Runedarth. Along the way, they hear possible fire beetles in the hills, encounter a tannery where they buy more leather and learn about several surrounding hexes, VS makes friends with Petunia the giant goat, and they make their way past Sapphire Falls to arrive safely at Runedarth.

Gemwin, Grom, Vindalf, Hokan, and Jendri team up with Nimira and some of her duergar to go after the green dragon in the dark lake at the bottom of Dragonfang Mountain. They cast several rituals, but as they begin to descend the cave slowly by rope, the dragon ambushes them with its breath weapon. At the bottom, a deadly game of hide and seek begins, with Vineslither the green dragon ambushing from water and hiding back in the murky lake several times. Gemwin is briefly attacked by an assassin vine, Grom heals everybody, Hokan learns to use a duergar firelance, Vindalf clings to the walls as an ape, and Jendri snipes at the dragon from afar. Then, in the huge lake chamber, Grom casts _Control Water_ and basically empties the lake, leaving Vineslither no place to hide. She grabs her egg from atop her treasure hoard and escapes downstream into the underground river, vowing revenge but abandoning her treasure hoard, including several useful magical items.

Jendri leads Gemwin, Grom, and Vindalf (Hokan is missing) to go talk to the Ironvein Duergar and explore a deeper level. Jendri offers Nimira and the other duergar some of the treasure they've gained, and they get a tour of the kitchens and the forge, which has a stream running into a deep chasm. Several of the duergar agree to hire on with the dwarves when they come back with a caravan in a few months, including the smith Snurriven and the alchemist Vorla. The party explores the chasm, first stopping on a ledge on the far side from the forge, where they discover a chimney with a rope and an escape bag. Delving into the chasm, they have a couple of close calls with Grom on the chain ladder. At the bottom, they discover another portion of the underground river, that leads to a dark lake with vines and algae. There they are suddenly attacked by a green dragon, who rises to breath poison on them before disappearing underwater again. They flee, but it breathes on them a few more times before they ascend the chasm to escape. Back up on the forge level, they recover, strategize, and offer a share of treasure to some of the duergar to help fight the dragon in its watery lair. Snurriven accidentally ruins Grom's new armor trying to repair it, and the party finds many situations in which Hokan would have been helpful.

Grom guides Gemwin, Vindalf, Jendri and Hokan as they explore a secret level that was the home of the gnome trapmaker of Khundrakar. After some trickiness with the first trap in a crawlspace, they encounter some hungry rust monsters and Grom's new plate mail is damaged. Further exploration reveals secret connections to the Glitterhame level and the mountain door, though most are gnome-sized and require dwarves to squeeze through without heavy armor. A bit of treasure, including a magical dagger, is recovered, and the party begins to consider how much of it to share with the Ironvein Duergar occupying the Forge Level.

Vindalf leads Gemwin, Jendri, Hokan and Grom as they continue to explore the former dwarfhold in Dragonfang Mountain, which they discover was called Khundrukar. They cast Speak with Dead to ask the former lord and master smith Durgeddin 5 questions, including "Can Grom use your Plate Mail?" Hokan does a bit of plumbing investigation on a derelict well, and they get more of the story of how the dwarf halls fell to orcs many years ago as they explore room to room. They speak with a half-crazy ghost, discover a portal room and the key word to unlock one of the portals to somewhere called Greywatch, and discover some secret passages that seem to lead to the duergar-controlled portion of the level. They discover a library and end up fighting an imprisoned lamia calling herself Idalla, and find a few scrolls and bits of dwarven lore to add to their collection.
