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 found some really good cliff resources. They have potential. I'll be using these cliffs in the Dibella's Watch landscape more later on, but right now, in Beta 05, they can be witnessed forming "The Arch" in the very north of the island. The models were made by Lordrahl.
