[ WP ] A peaceful alien race is besieged by another race in the same galaxy . As their last planets fall and their home-world comes under threat they do the unthinkable . They ask for aid from the only known creatures more brutal than their foes in exchange for FTL technology . Humans accept the deal .

We had no choice. 
 
 We were an ancient race. We saw Galaxies form and be consumed, we saw species rise and fall under the weight of their own will to survive, we saw entire universes begin and end... But we never saw them coming. 
 
 Our species had reached enlightenment eons ago, from then on we traveled the multiverse helping species advance to what we knew to be the enlightenment we achieved. We spent millennial nurturing, protecting and teaching them. Some were accepting, trying to reach the high goals we set for them. Others were insidious, using our eternal knowledge only to further their own agenda. All, unfortunately, perished. Some failing the test of evolution and dying out while others had to be eradicated lest they pose a threat to other species. 
 
 The Kariir were the best and brightest. They learnt, grew, practiced what we preached and we kept giving them more; information, wealth, they never had enough. Yet somehow, they never attained enlightenment. We should have know. Maybe it was our desperation, finally having a species grow so fast and be so thirsty for knowledge. Perhaps we were too excited after the countless failures that we did n't see the signs. Perhaps they were too cunning even for us. 
 
 As our cities fell by our own knowledge, as our vast system crumbled, we could only watch with horror as malformed versions of our own creations consumed us. It had not been knowledge they looked for, but power. They had not reached enlightenment not because they could n't, but because they did n't want to. As even our eons old strongholds fell and we were pushed back to the single planet of our origination, our council met in desperation. It was agreed. We had no choice. 
 
 A single ship was sent to the quarantine zone. A small solar system surrounded by a field that blocked all communication and all detection, from inside and out, to all eyes except our own. Inside this zone was the most deadly disease we had ever come across. With just bare levels of consciousness, this parasite burrowed into a host planet, sucking it dry faster than any species in know existence. It called itself `` humans'' and upon first sighting had immediately been classified as the most dangerous plague ever to have been discovered over the know multiverse. In the time it took a regular species to develop it's first language, this species grew into a full fledged civilization, attained near super-light travel and annihilated itself a hundred times over. They were quick to learn, violent and ruthless. Although a ( barely ) sentient species, they were classified as a plague due to the level of damage they could cause to planets should they escape the one they inhabited. With no regard for life, the only thing keeping them in check was the availability of only one planet they could devour. Should they spread, all necessity to keep their planet alive would be gone and entire universes could be lost. 
 
 We had no choice. The ship docked at the planet. 
 
 As with all plagues, less exposure was better. The crew of that ship knew what the signed up for. They were never seen again, doomed to spend the rest of their miserable lives being tested in all manner of horrific ways. From then on, we just nudged the humans in the right direction. We phased all remaining friendly systems with sentient life out of the humans observable reality for what was a mere heartbeat for our species and when we returned, the galaxy that was once full of life, even Kariir life, was gone. An entire universe was but a collection of husks of dead planets floating in a void. We survived. All was good for us. Or so we'd like to believe. 
 
 But we know, somewhere out there, life is being ended faster than it can begin. Somewhere out there, a species is building it's first radio transmitter only to be descended upon by a plague. Enslaved, raped, tortured; their world turned to ash. We had won the war, but lost so many species in the process. 
 
 We tell ourselves we had no choice, but we chose us over them. All of them. We'd doomed ourselves to a lonely existence, being the only race immune to the disease spreading across the cosmos. 
 
 Humans. 
 
 We had a choice, but we chose us.
