So after building the merchant her store, behind the building will be a note and talking to her will produce a short CS where she asks you to deliver these 4 items around the map.
To the woman who owns the farm just southeast of Lincolnscire's southern bridge
Jar of Rosewater Mead
To the hermit hut at the feet of the mountain, north of Sabrina's spring in Glowecestrescire.
Crate of Bowls
To the jewel maker in Ledecestre, between the church and the old Roman bathhouse.
To the blacksmith in Lunden. His workshop is near the church, close to the west gate.
Now fortunately these items can be placed on your boat, but you can ONLY CARRY ONE AT A TIME, they will despawn and respawn behind the shop if you get too far from them. Also, these directions are super vague and Odin's sight does nothing to help. I managed to find the blacksmith in Lunden, who is not quite near the west gate, nor the church (his shop is in the wall north of the west gate, the church is closer to the center of town, so not helpful at all). I was only rewarded a measly 40 silver, garbage for the amount of effort carrying the stupid anvil all the way to Lunden and searching for the NPC, but I figure there's likely a reward for doing all 4.
I'm currently stuck in Ledecestre looking for this jewel maker who I am beginning to believe does not exist or might not until I do the Ragnarson questline first. If anyone knows anything about this "jewel maker between the church and the old Roman bathhouse," please let me know.
