Hopping back in time is what I would consider godmoding. (And it did kill some plotlines I had in mind. Plotlines about Sith artifacts which hit the markets because of the chaos in the Empire.)
You should have asked and I would probably have agreed.
I'm not going to subject all new players to go back and read 5-6 threads worth of info just so that they can be on equal terms with us. If they wish to, they can go and read Formal Apology, but I will NOT force them to. I'm sorry I killed some plotlines. But since you obviously had more than one, it can't be too hard to adapt one or two.
And since you would have agreed anyway, it all worked out in the end.
(FYI, there's still PLENTY of Sith artifacts lying around.
