Trip to Volarium

I don’t understand… 

One minute we’re on a train to the city, and the next, we’re speeding through galaxies toward some distant planet called Volarium?!

I mean, how are we even able to breathe? 

And what exactly are we in, if not a subway car? 

And what exactly do you need me – a full-time accountant and volunteer firefighter for? 

How do you even know who I am? 

In short, WHAT THE HECK IS GOING ON?!?
