DnDNerds!

Neville Cavendish puts together a crew for a heist, featuring Flip, Kain, Brimlad the Brawler, and the return of Lysander. A Goliath gang leader sends them on a city-wide scavenger hunt before taking them to Grathka Stonevein, who wants an important ceremonial ledger stolen from the Black Network. She has them meet up with her inside source and a strange wizard to aid their preparations. During the heist, a huge stone colossus rises up from a magical circle to do battle against the party. Narrowly escaping with their loot, the party help stage a scene to blame the crime on some of the guards and on a rival adventuring party, the Black Cats.

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.
