Klopstock
A family — a name on a ring. Among the stained blankets of the Worship Hall in the Sepulchre of the Swamp Witch lies a ruby ring inscribed with the name Klopstock, worth 200 silver to most merchants but, if brought to Schleswig, the only surviving Klopstock family member pays five times as much (1000s).

Gaps / Expansion Notes
Source names only "the only surviving Klopstock family member" — no first name, no description, no story. How the rest of the family died, who they were, and why a single ring matters so much to the survivor is open.
