The first homebuilt Branan spaceships were slow affairs, propelled by rocket boosters and using spin sections to generate gravity as they traveled between the nearby planets. The Albion shuttles had their own gravplating for internal gravity, but the Branan couldn’t duplicate that technology, so they made do with ships not far removed from those we used to explore our own star system. It would be decades before they improved their ships enough to brave the depths of the Betelgeuse system and navigate to the other two gas giants orbiting their home star. They spent decades more colonizing the planets orbiting those giants as they continued on to explorer the outer reaches of their star system with better and better spacecraft. And then they decided it was time to follow their creators into the interstellar deeps.
