Under the Table

Walkthrough
Visiting the Black-Briar Meadery in Riften, the Dragonborn may discover a memo to the employees there entitled Attention Employees!, regarding recent mead barrel thefts.

Speak to Romlyn Dreth, a worker at the meadery, only to find out that he is actually behind the thefts, and that he has been selling off the mead at a lower prices. Found out, he offers the Dragonborn a cut of the profits, if the Dragonborn helps smuggle the mead out of Riften and brings it to a customer.

Deliver Mead to Wilhelm or Show Mead to Indaryn
The Dragonborn can now either go along the smuggling routine, and deliver the mead to the innkeeper Wilhelm at the Vilemyr Inn in Ivarstead for some levelled jewellery. And then return to Romlyn, for more deliveries.

Or, rat out on Romlyn, by showing the mead to Indaryn his boss. The latter rewards your "honesty" with levelled gems. Unter dem Tisch
