The year is... way too many.
Humanity and the others out there have littered everything with their technology and their junk in general. Now even space is clogged.
One day the universe decided it has had enough of it and wants to build something new.
But for that it needs space. More space in space. Which is a bit weird...
Anyway...
The universe asked you, personally, for help. It scattered black holes here and there, they already cleaned up a good chunk of the mess but they need a hand with the rest.
