Actually, if you had read the novel "The Infernal City" (which IS official cannon) you'd have seen that he was taken into Oblivion. This caused the Ministry of Truth to fall onto Vivec City and destroy it (it's only kept floating by Vivec's magic, and since he's no longer in Mundus, it fell). He may or may not be alive, but he WAS taken in Oblivion. That's not a rumor, it's cannon.
