I was thinking about the Revanite quest shortly after I wrote about Charnus, but then I remembered that months/years have taken place in-game between when you essentially frame him for being leader of the Revanites and when you meet him on Corellia. Clearly, he's not been too troubled by any accusations leveled against him on Dromund Kaas.
Though Beniboybling mentioned Darths Gravus, whom I had initially forgotten about. Now that I'm thinking about him, IMO, Gravus already has the air of someone who belongs on the Dark Council, so I think he would be another good candidate for a promotion.
