Would anyone be interested in a murder mystery, set just before Oblivion, about the death of Vivec? I think I proposed the idea awhile ago, but I don't recall what kind of feedback I got. We'd probably play as agents of the Temple sent to track down the assassin, as well as helping to try and keep his death under wraps, but we could end up recruiting non-Temple characters on the way.
According to most commonly held canon, Vivec disappeared into Oblivion. It is not believed that he just was murdered. Either he vanished and became NULL like the Dwemer, or he was essentially voided by the Daedra. Or maybe he simply disappeared, in order to reappear at a time that people would want him again.
It's hard to tell the mind of a powerless false god.
He had a lot of enemies, and his biggest ones were not mortal.
Could be an interesting murder mystery if you pulled it off though...
