someone could say its post darkside Anakin (which i guess would technically be Vader) but have him join up with Dooku...doesnt matter. The main reason I said that is cause i figured that most people would say that Dooku just owns people waiting in line and i didnt want to deal with the fanboyism of that, but you can use any scenario you want.
Also if you all want, you can come up with an agreed upon setting and match and do it that way.
