Madach Room Key?

[cryocry]

This may have been answered in the seventy page long topic about what your charactar is like, but I didn't want to go through seventy pages of stuff to see if it was answered. Anyway, here's the question:

 

I bought a key called the "Madach Room Key". I'm just wondering what it goes to. I looked at every door, but they weren't locked. I even looked in the room with the Argonian guy, but I couldn't find a door in there, either. I even looked behind What's his face Madach. What does the key go to?

I have wonder the same thing; it does not unlock anything or free the Argonian. I am also wondering, why is it for sale? That does not make much sense either, considering it is an inn, technically, even though there is no vacant room as well. My only guess is that it could be a con by the former thief he is, since the key costs a few hundred gold, but more likely, it is an unintended mistake by Bethesda.

It could also be intended to denote that "I buy keys!". I'm pretty sure I've sold off my used slave keys there on occasion.

Hmmmm... maybe I was right that it doesn't go anywhere. But what if it was mis-named Madach Room Key, and was actually intended to be found else where, and part of a quest or easter egg or something?
