You could come up with a little story line for your character so that he lives that long but kind of has to "get back in the saddle", or link your new character as a descendant of your oblivion character... if you're that involved. And as you're already here on the forums... :deal: haha.

I've made tons.
I started out on Morrowind several years ago. Loved it ever since.
