Maybe that's the thumping upstairs I hear sometimes when I enter Birna's Oddments.
How, might one inquire, do you get INTO Birna's in the first place? She and whatshisface are always standing outside arguing (even after I "fix" his problem with the innkeeper).... with the door locked - and waiting through a 24 hour cycle never shows them elsewhere or the store "open for business".
[And yes, I did buy the claw from Birna and go do that stuff as well....]
