This is something I've never fully understood - Was the ancient subspace tracking technology neccesary to know where the lucifer was going to be in FS1, or was it more directly neccesary for the final encounter - ie. Without it we would not have been able to attack Lucy at all. I know that the Ancient revelation that "In subspace they cannot use their shields" would have been important, but was subspace tracking a requirement of subspace combat? It's for a bit of shivan related internal fiction I'm doing up for TI, so it's not amazingly important I know right away, but if you know, please post.
