i noticed a few things that could be used to create an "unofficial" expanion for jk2.
1) Cairn was never destoryed, they can still produce shadow troopers and everything.
2)the apprentace was never killed, and without desann to fear, she can take revenge on kyle. she also knows where the valley of the jedi is located.
3)Desann was no fool, he wouldn't have 1 ship when after the invastion of yavin, the new republic could destory it easily. He probily had a few star destoryers that his apprentance could use for revenge.
4)kejim base is still there, with a few cristals lying around. Kyle didn't take them all.

think someone could do this?

1)True But Kyle Told Lando about it and he could have called new rep forces in to blow it

2)I Didnt really think she was scared of desann she would be with kyle

3) cant argue with that

4) I thought everyone died there
