Jack held fast to the controls of the ship as they plunged into hyperspace. The g-forces on his body pressed him into the chair, and he focused all of his attention on keeping the craft smooth and flying. He'd worry about just where it was they were going later.
It was a strong craft, a good ship. But it was built for leisure, built for transporting rich people to unimportant places. There was no hardened shell and it wasn't well shielded, and so it wasn't ever constructed to contend with such difficult conditions. It was something like trying to drive a sports car through the desert in a sandstorm.
The ship started shaking as they moved through space; fixtures and fittings coming unstuck from their various homes in the craft. Somewhere inside there was a smash as a vase fell from a shelf and not even the gravity cushion was enough to restrain it.
"Make sure your trays are in the upright condition and your seatbelts are fastened until the pilot has turned off the seatbelt light," Jack said with a grin as he moved the craft along. There was an undeniable rush with it. The thrill of the adventure and the danger. You really had to be a certain sort of person to enjoy it as he did.
Jack had seen the vortex before. Travelled through it, even, clung to the outside of the TARDIS. The Doctor had seen it too, many times, Jack suspected. But the Doctor didn't need to know that right now. So Jack leaned forward and pressed a button on the panel that blackened out the window in front of them so they wouldn't have to see the vortex now as the vortex manipulator directed the ship through it.
"Hold on tight!" Jack called as they travelled. Just a little longer, just a little bit more. The ship continued to rattle and he worried it might not keep together, but then without warning or sign the shaking stopped.
"We're out," Jack breathed with a wide grin as the adrenaline rushed through his system. He reached forward and pressed the button to clear the glass. What he saw outside wiped the smile right off his face.
Below them, a few hundred feet or so was the surface of a planet. A planet covered in a dark cloud, devoid of light and life. It looked sick, like the planet itself was rotting. It sent a chill down Jack's spine.
"So don't tell me," Jack said, "The Death's Spiral, right?"
