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!
The waters of the Idyllic South may seem pacific, but there are several shipwrecks dotted around, which means it ain't that pacific after all.
I love shipwrecks. :D
So do I! I will have several of them.
