You see? This is why you should pay attention to whose quests you pick up. You agreed to take shirts to someone in Ald`ruhn. I suggest delivering the argonian's shirts. Otherwise, no more shopkeeping, no more fast travel.
Morality is relative and based on opinions. Everyone has a different opinion, so everyone has a different view on what is right or wrong. What is right?
BTW, I have enjoyed your other posts. You are a gentleman and a scholar. Please believe me, if there were merely mountains I could move to assist you, I would turn the Rockies into the Great Plains. But without the shirts, to the best of my knowledge, there is naught that can be done.
Not just any 5 Exquisite Shirts will work for that quest. If you cannot find the shirts that Rasha gave you, then you'd better hope that you are playing the GOTY Edition. Why? Because, Ten_Tongues Weerhat, the Pawnbroker in the Bazaar in Mournhold, is the only other source for those same shirts. And, he has 5 of them for sale.
This is from my journals, and I have yet to see it mentioned anywhere else.
