Hmm, definitely an interesting space battle so far and I'll be interested in seeing how this one develops now that all the players are there. It'll be interesting to see if what Harry's already mastered of Battle Meditation can affect this battle. The set up for the battle itself looks decent and you give a good thumbnail view of the battle (unless you can write space battles like David Weber, it's probably better that way). It'll be interesting to see if any of the tactics developed in 3D throughout Earth's history (submarines and aircraft) that Harry may know about will have application here. I do agree with Vanir about naming the ships after goods of war (Marduk, any one?).
Aa for a female aspect of the Force, perhaps it (she?) should come off as a mix 'tween Hermione and Ginny, but knowledge and emotion mixed together but focused rather than dissapated lavendar Brown or Pansy Parkinson appear to be.
