Why didn the starborn stop the collapsing of the Gamma Draconis – Capella jump node. They did want it to remain open, didn they?
The shivans have other ways into GTVA space and the Starborn were too surprised by the shivans blowing up Capella to do anything much about the GD-Capella node. Also: The collapse of a jumpnode is a minor inconvenience to the Starborn. It merely means that a Starborn has to use a little more energy to get to (or from) subspace. Any jumpnode was originally just a weak spot in the energy wall between subspace and normal space. It became what we recognize as a jumpnode by the Starborn using it as the easiest path in their travels. The Starborn will simply find another nearby weak spot and start to use it. After thousands of passages, the new spot may show up on the Shivan Groupminds sensors as a jumpnode. After hundreds of thousands of passages, GTVA sensors will also register it. As far as the Starborn preventing anything, keep in mind that the Starborn have very little physical presence in the universe. They are best thought of as energy beings. While their ability to manipulate energy
