Missing Guildmate
The merchant you traveled with offers you a few sticks of cinnamon at Buckthorn's request.
During the trip, Idi casts his divination. Your vision shows you a bird's flight view of the White Sword Province, heading east along the Moonstone Stream. Then, moving lower, you see a small alcove in the Sunrise Reach, where a lone Dwarven building stands, almost hidden.
Looking at the architecture, Spriggy realizes that although built by humans, the architect was actually a dwarf, something rather rare this far north.
There are plenty of people around that seems like they would love an excuse to take a break, or you could ask at the manor directly if you prefer.
