As the cool kids say: things are getting lit, fam.
I had forgotten all about the Beyond Skyrim: Cyrodiil project until I came across this just a short while ago. By the Nine! I am eager to try it out!
According to the video, it looks like they are adding a whole bunch of other stuff too beyond just the area to explore, such as new spells.
This reminds me: I have a confession to make...I have never once used an Elder Scrolls mod. Ever. I'm not inherently averse to it; I've just been too lazy to configure one to run and I've had games in my backlog that I want to get through. Looks like this will be the first though, because I have to try it out when it releases.
