You can walk through a door at a location of your choice and end up in the doors location in a random story in a random universe. Where would you put that door?

I was wondering if people in this sub would have a better answer than people in other subs. <br><br>One idea I had was to put it at the edge of the solar system. The story starts with a space ship slamming into a door made of wood and cancelling its interstellar journey. No idea where the door leads.
