[ WP ] In the near future , mankind explores the stars in search of life . Life indeed exists beyond Earth , but you , a researcher on a science ship , discover that all of the spacefaring alien civilizations died out . Curiously , their deaths seem directly linked to humanity reaching outer space .

`` Welcome Hominid. Kindly speak your name to continue.''. 
 I gazed at the glowing slab, it reminded me of my 50' t.v back home. It was the only relatable thing in this alien structure. 
 `` Special Lieutenant Cooper. Adam Cooper, from the United Earth Directorate. Earth. Sector 4, from the Milky way galaxy.''. 
 
 `` Welcome Adam Cooper. Kindly wait while the interactive cognitive program loads.''. 
 
 `` Good morning Adam. I trust the voyage to our planet was pleasant. My name was Griffin when I encoded my consciousness into this welcoming station.''. 
 
 `` Griffin, eh? Good morning. It seems Griffin, that you were expecting us. But why a machine to welcome the alien guests?''. 
 
 `` My apologies Adam. It may seem cold and uninviting, but I assure you we have a very good reason for this welcome.''. 
 
 `` Well, the first question is how on earth..err, Gliese 4b, are you talking in English?''. 
 
 `` Haha! A good joke Adam. You have just discovered our planet and have finally managed to travel here. We have been observing you for millennia. We left instructions with your greatest civilizations to contact us when we visited for the first time. However, it seems we were too obtuse. We sent our scouts and scientists every Earth century to try and explain our presence and intentions, as we have done with many other races across this universe. W-''. 
 
 `` Wait! The alien abductions were real? And there are other intelligent races in our universe! Why did you not tell us properly?''. 
 
 `` That is correct Adam, the universe teemed with sentient life. We did n't --''. 
 
 `` Wait.. teemed? What happened to it? What happened to you?''. 
 
 `` You are quite perceptive. It was something we did not anticipate. The Hominid body contained such virulent parasites. It caused us to change. We unknowingly transmitted the infection to everyone we came in contact with.''. 
 
 `` What? You caught our germs? What happened?''. 
 
 `` It caused an increase in agressive tendencies and diminished pain sensations. It spread via bodily fluids and resulted in a massive civil war. Only a handful of us, the protectors of knowledge, were left alive. We were infected, but managed to erect these welcoming plaques in 5 different galaxies in the hope that you hominids would eventually reach the stars. I wish you the best of luck. The baton passes to you now for this universe. Care for life, it's the most precious resource of the universe..''.
