Expedition
Overheard in the tavern: "It's not that far away. 'Bout 30 miles out toward the Numuad Hills, it is. Old dwarven trading post, what's fallen to ruins, it has. They say what's on the surface - which ain't much, I'll grant ye - ain't nothin' compared tae what's down under the ground. Ye know them dwarves like tae dig up under the ground. I'll betchye there's jools down there. 'Nuff to set yerself up like a lord for ten lifetimes, I'll bet. Just gotta go to old Zzietokk. One o' these days, I'm goin' there. Ye'll not be seein' me 'round here again after that, I'll bet."
The party, without any particular work or direction, elects to investigate the old abandoned dwarven trading post of Zzietokk. There, they face environmental hazards like brown mold and more direct hazards, as well, in the form of phase spiders, trappers, and a grell. They overcome these challenges and find a small amount of reasonably valuable treasure left behind by defeated adventurers. All the good old dwarven goods are long gone.
