I remember some months ago seeing a mod on the forums that was creating a new world for Skyrim, I think the user who was making it had a P at the start of their name, like prometheus possibily. The mod seemed pretty huge, it had a lot of posts on it's thread, and the work put into it seemed really impressive, I just can't find any reference to it anywhere though, I assume someone might have an idea of what is is, seeing how big it was and how much attention was drawn to it, but for some reason I can't find a trace of it!

Ah yes, that's the one, thanks!
