Ah, right. At some point he ends up there, though. The Legacy
comics established that Jag would be declared Emperor, institute a Fel Dynasty, and establish the Imperial Knights order of Force users.
By the end of FOTJ, I was much more interested in Jag's story and all the political machinations inside the Empire than I was in the Abeloth and Sith war.

You have a point. I didn't include it above, though, because I don't feel that her actions there were necessarily tied directly to Jaina having been dubbed the "Sword of the Jedi," whereas, if I recall correctly, she used that title as part of her justification in LOTF for being the one to confront Caedus.
