Speaking to Dravin reveals that there was a recent break-in at the farm. Among the loot that was pilfered was Dravin's Bow. He believes the Thieves Guild was behind the burglary and that they stashed his bow somewhere in the Ratways beneath Riften.
The Dragonborn is tasked with retrieving Dravin's Bow from the Ratways beneath Riften. He rewards some gems that may help with Madesi's task. Also, if Dravin is killed after the bow is given to him, a courier will deliver a letter and some money.
What happened to your bow?"A few days ago, some thieves from Riften broke in here and stole it! Can you imagine? Took the only thing of value we had. If you have the guts to head into the Ratway and get my bow back, I'll pay you what I can."
I'll see what I can do."Thanks. It would be nice to have it back... means a lot to me."
You've had trouble with thieves?"Are you kidding me? We're all alone out here except for a few guards who couldn't give a damn about us. We make easy pickings for thieves looking to steal everything we worked so hard for. Not only did they take my bow, but they took all of our coin as well. Nothing's sacred to these people."
How do you know the thieves were from Riften?"I bumped into them when I was coming back to my farm after buying supplies. I know those lowlifes took it with them back to the Ratway. They left an unmistakable stench behind. It was a family heirloom. I can't even put a price on how much that thing means to me."
"The Ratway is somewhere under Riften, shouldn't be too tough to find."
Sorry, I try and avoid thieves."Fine. I'll wait until someone else with a little more courage comes along."
After retrieving the bow:
"So, has my bow turned up yet?"
I found your bow."That's it! You found it! I don't know how you got it back, and I don't want to know. Frankly, I don't even care... I'm just so glad to see it again. Here, this is all can afford to give you as compensation. Hope it's enough."
