Max's team was hard at work on the creation of the intricately detailed alloy shell for the Dyson Sphere, as detailed in the ancient human plans that Ranarth had provided, when an idea came to Max.
There was a flash in his memory of a long forgotten repair process, not even on a Mecha, but a relic starship from his youth that he had purchased in order to sneak away on vacation. It was even more derelict than Terminus was when he first found her, but the Warp Drive used a Dyson Sphere similar to the one that they were constructing, only it had once contained a self-sustaining star inside that had been purged when the ship was decommissioned.
The images flowed through his mind of years spent trying to get the wreck to fly without getting caught with an unregistered space vessel, and Max realized that he actually knew the basics of the design that they were trying to replicate quite well.
