Liftoff!

No aliens, Zee. With one exception, all the people aboard the vessel are human. Well, humanish. One's a human-descended abhuman ratling, and another is from a low-gravity world and requires a support frame to stand and move in this standard gravity.

The antique diver, cosmonaut, Militarum vet and low-grav person all take positions as determined by the tech-priestess and strap in, preparing to launch. Her voice comes over the intercom, asking everyone to strap in and hold on tight. The Gunners and other crew do so; the ratling is holding on with one hand, the other hand holding a roast partridge leg that he's chewing on, quite unconcerned. The Gunners and Gunslinger haven't been to space before, and are notably more worried. One is space-sick.

SPAAAAAAAACE!

It's a bumpy ride up, and the crew are panicking a little, but trying not to let it show. There's about five seconds after they enter orbit where the power cuts out, and it's dark and the artificial gravity cuts out. The ratling is the only one who isn't too worried at that point, just still eating. The tech-priestess manages to get things back in working order, however, and they rocket off to the Hammer of Finance. Assuming Zee and Minerva are on the bridge, they can hear the tech-priestess' words through the intercom from the engine-chapel. "This is odd. I am not picking up any vox transmissions from the vessel. Not even trace transmissions from one deck to another." As they approach, the Rogue Trader vessel grows in the windscreen (spacescreen?) as the shuttle is driven towards a docking bay.

Zee might not be able to tell, I don't know how far she can read world-lines, but... there's not many on the ship. Far less than their should be.
