Dibella's Watch adds an entire new continent to Oblivion. It comes complete with a major city, castles, towns, villages, farms, monasteries and all the good stuff that makes up a Medieval landscape. There's also fighting to be had and quests to be made!
I still can't upload Beta02 to ModDB and noone's responding to my forum posts about it either. Therefore, you have to get the latest update of the mod from TesNexus instead. Tesnexus.com
