Disorderly Traveler

I am a "walker", that's what I call myself. The job I do is actually nothing unusual, I just deliver things between parallel universes, like an interstellar Lalamove driver, except that my car is a shabby electric car that is disguised and can open gaps in space. This job earns hard money and risk money. After all, you never know whether what is waiting behind the door is a client or a group of thugs with alien weapons...
