AU: Bilbo is corrupted and joins the Nine Not yet corpses. Still, we rot. The Ring decides that Bilbo Baggins is the perfect consort for Sauron. Problem is, a: Bilbo is a mortal and will someday die, and; b: he does not know nor love Sauron. So, the easiest way to solve both problems at once is to make him join the Nazgûl.
