In a sense she is no different from Sion, a corpse who is somehow able to walk around, only where he is dead in the flesh, she is dead in the Force.
Doesn't it require the force to leech the force. And Nihilus as shown that he gets weak if he does not feed on the force after so long. So even wounds require the force to live, right?
