Anyway, this is our first windmill interior! It might actually be the first windmill interior ever in Morrowind, though you shouldn't quote me on that. (Seriously though, did vanilla have windmills? I haven't played this game for such a long time...)
Not a big deal, really. It has wheat, gears, clutter and flour. I decided to claim this bad boy this evening and quickly finished it. The interior really is small. I took 3 screenshots and I think you can see everything on these that there is in the whole cell.
