Can anyone recommend some mods to add locations outside of the default boundry? I've edited the ".ini" file to allow me to go outside the default area. Also, I've installed Riverhold, which I like. Anyway, it'd be nice to collect all this information into one place so we can all benefit from it.

Replace Riverhold with http://www.tesnexus.com/downloads/file.php?id=25023 - it includes everything that Riverhold does and a whole lot more.

O sweet. Man am I glad I asked here.

An Alyeid ruin/HQ, a city, and maybe some other things... but they're just barely out of bounds.
