They hadn’t planned, though, for the last-minute addition of the heptad from the Swarm. This was awkward. It would be connected to the Stack by a docking port, which wasn’t designed to take a lot of mechanical strain. It was heavy, because Aïda and her crew had crammed it full of supplies and strapped even more to the outside of it. For the same reason, Ivy didn’t want to just ditch it—they could use those supplies. So the plan had been for three spacewalkers to greet the heptad and lash it into place with cables as soon as it arrived.
