Also, beyond the boundary of Phase-Wave, the same expedition finds a weird new planetary system, which included three planets which were in what Earthers called the "Goldilocks zone" of the system - the area of space around a star that had just the right conditions for life to flourish. There were two problems with these planets: the three went around their star in the same precise orbit. And they were all frozen. And they shouldn't have been frozen.

And then, on the one they called Terra Dracones, they find an ancient structure under the ice that contained Earther and Elyran statues.
