Greetings. I stumbled upon this thread while googling for an ancient Uvirith mod (Village of Mora Uvirith) and feel I should commend and comment on this work in progress.
The screenshots look wonderful and I'm eagerly waiting for more. I just hope it will be compatible with Town of Uvirith (best Uvirith town mod so far).
Finally, while there has been no official word about the "real" Uvirith, there is another mod around which has an - imho pretty good and very lorefriendly - history of him in a book:
Rise of House Telvanni - Planet Elder Scrolls
Other appearances in Uvirith mods typically have him as a vampire who is quite hostile.
