Issue #31349: Geldis Sadri at The Retching Netch tells you to check out Thirsk Mead Hall after completing quest
I finished the Retaking Thirsk quest and got back to report to Kuvar. Then i got to The Retching Netch to ask Geldis Sadri about rumors and he told me that the nords have been exiled from the thirsk hall and gave me 2 markers, one in front of the mead hall and another one at their previous camp location. The objective is under misc quests and says: Investigate Thirsk Mead Hall and the exiled Nords. I got to both locations and tried to talk to all of them but the markers wont go away.
