[ WP ] You are part of a team that investigates the post-apocalyptic ruins of a city on an alien world . A discovery there may change the course of human history .

After much debate we have decided to make landfall. This seemingly alien world is strangely familiar. Infrastructure, structures made of steel and rock, dry aqueducts that once distributed water to a now dead city-state. It is difficult to imagine such a spectacle unfolding much differently on Earth, the world we, humanity, once called home. 
 
 We have been searching the cosmos searching for an explanation to the age-old question, `` are we alone in the universe?'' It can not be refuted that this question has now been answered. Though the answers we seek were answered in a most unfortunate, and troubling manner. 
 
 While the planet is dotted with many of these seemingly primitive cities, not a single biological life form has been detected by our systems. Industry not dissimilar from our own is evident across the landscape; the heavily exploited surface leads us to conclude that the populace had completely exploited their natural resources. Strangely, the products of which have been found to be missing aside from empty structures. 
 
 We began searching for an answer to this troubling puzzle of achievement without result. Upon closer inspection we came upon a subsurface structure hidden under the remains of a ruined city. The ambient surface radiation that pervaded the landscape spiked dramatically. Within the depths of the alien construction we came upon the sum of all fears. We discovered a single object, not unlike the weapon that forced the exodus of our world. 
 
 The object was a neutron bomb. Suddenly, we realized that our near-extinction had claimed yet another semi-sentient race. It was with a heavy heart that we left yet another desolate world, cursing the invention that had ended the only other intelligence we humans had ever discovered.
