As the first use of the super-plotdevice-communicator thingy is turned on to reach the stars, they get a call back while the unveiling conference is being done. The response received:
"The fuck do ya want?"-a slurred voice came out in perfectly eloquent english.
After a few tries to confirm that the transmission is coming from, the presenters tell the voice the usual first contact bs.
"Congrats I guess... Just go to the local spaceDMV and get registered like everyone else. Now fuck off. I got a delivery to complete and I'm not in the mood to get into 1st contact politics. Btw, welcome to the empire. Your about a third of the territory in. The capital planet is like right there."
How will humanity react? Is space really not the final frontier that everyone thought? (Yes. The empire is prolific and everything in this arm of the galaxy has been explored to the extreme.) Is Earth now a vassal state? (Earth is in their territory.)
