This is probably going to come as a shock to imperialscum, but there's something about TOR that I actually do like and accept as canon.

I love the idea of Sith sleeper agents -- entire families of Sith sleeper agents -- operating within the Jedi Order, working behind the scenes for centuries to undermine the Order and bring about a rebirth for the Sith.
Of course, I still don't accept the brouhaha about the Sith Emperor and his reborn Sith Empire. I'd have Ovair and his fellow spies be the descendants of followers of Exar Kun who infiltrated the Order during the Great Sith War, instead.
