I'm not a fan of 'prequalism' but the LOST TWENTY was something that was never properly fleshed out in the prequals, maybe there are still a few floating around that aren't necessarily fallen Jedi, but they have conflicting ideas to Luke's . It's hard trying imagine a new Big Bad that could compete with Vader, even if the prequels destroyed his character

I'm not exactly fond of the Lost Twenty, mainly because I find the idea that only twenty Jedi would ever leave the Order due to a difference of opinion pretty stupid.
