Just curious. I have a feeling it will be very superficial. More like how Cheydinhal's Architecture was supposedly influenced by the Dunmer. It claims that in game btw.

Probably not much because the town was there before all of the Dunmer were.

They have been neighbors with Morrowind for over 3000 years...Oh and there must have been a HUGE influx of Dunmer after the Red Year and the Argonian Invasion.

It's also the rebel capital. About 500 years before Skyrim, it was also the area that was most Nordic in culture, but that was a looong time ago.

It's also the largest city in Skyrim. I hope they don't turn the biggest city into Morrowind.
