Aggie is correct, but Legolas is also correct that it would not work if she is removed or otherwise not in play.
Her ability is a delayed target, activating after the battle and attempting to capture her. Capture is limited to play. Since she does not have an instead ability associated (like Assyrian Survivor, which says "if defeated," or other cards that say "regardless of battle outcome," where a state is being replaced to something else INSTEAD), it is just that delayed-target-capture. If she is not in play (removed from game, shuffled, returned to hand, set-aside, etc.), she cannot be targeted for the capture. Also, if she is captured, she becomes a "captured character" and cannot be targeted as a "character" any longer, meaning she would not move to another Land of Bondage.
Hopefully that answers all of the questions.
