Before entering the planet, I had witnessed hundreds of other spaceships flying between the various moons and the giant planet. But they had a different feel to them than our Nimbus.
I asked my mother, who was standing by my side, about this.
"Mother, all these ships don't seem to use the same engine as ours. What is that?"
"You caught on quick darling~. Only a few ships like ours are able to create our own Spacetime Tunnel to travel. And the other mass-produced ships, like the ones we just saw now, don't have the 'mysterious crystal' like Nimbus, so they are unable to travel through Spacetime Tunnel on their own.
The only way they can cover a large distance quickly is to use the 'Spacetime Portals'. These portals are built near major strategic planets such as the Lindstrom."
"Oh, I see."
