[General Science Fiction] So uh, we're a 100,000,000 million year old intergalactic civilization. We're constructing intergalactic bridges to allow our people easy travel between galaxies. But these primitive locals are trying to get in our way. How do we solve this issue short of galactic genocide?

Seriously, in one of these galaxies, this 'Galactic Empire' keeps trying to shoot at our bridges with their death moon thing. 

In another galaxy, an organization called the Federation keeps trying to contact our construction ships, but our Prime Directive prevents us from talking to them. 

And in another galaxy, these blue-colored females analogues, birds, and reptiles keep asking us to join their Council.

And don't get me started on this one galaxy, one that seems to be in perpetual war, filled with all manners of weird things, from giant armored humans, to ugly evolving insects, and demons and elves. We should probably stay away from this one, but they're so close to the other clusters. 

We've tried making the bridges invisible, but as primitive as they are, these galactic societies are still advanced enough to detect them.

Fake your own extinction, go into hiding, and pretend it never happened.

Bonus points if you take bits of your miraculous technology and use them to leave the greatest scavenger hunt in the universe.
