Sorry for the bump, but I was recently married to the lovely Brelyna Maryon and felt I had to share. We had just three guests (though I'm known all over Skryim). None of our friends from the Mage's College showed up, which as Archmage, I took note of. Argis the Bulwark came, an old buddy I was glad to see, and next to him was Athis of the Companions, who I've spoken to about once.
On the front pew, though, and the only one who congatulated me on my marriage, was Ondolemar, the Thalmor consul in Markath! This was quite an embarrassment, of course, being deep in Stormcloak territory. Brelyna understandably ran out of the temple before the ceremony was barely over, and before I could give her all the enchanted jewellry I'd made her. Took me ages to find her again.
