hi all- I'm playing through my second time as DS, and i'm on my third planet, nar shaadaa. When playing LS i know you can get the lens for your lightsaber from the "reunification" quest, but since i'm dark i didn't do it, and therefore am lost as to how to obtain a lens. I have all the other parts; a lens is the only thing i'm missing. Any help on this would be great, thanks.
