Grey-scape

In the agricultural plant of Soralis II, Vena, lives Grey Marshall, a 17 year old male, strong willed, and physically strong, though he did not have a great physique. he was somewhat different to everyone around him, and for most of his life he lived peacefully in the rural meadows of Vena due to his birthplace. His family only consisted of him and his Dad, where they live in a large town outside the entrance towards the city.
On an afternoon, towards the end of a specific celebration, loud booming noises polluted the sky of Vena and Grey ran out from the steel gates of his home and watched in horror, as the sky scattered in multiple derections, raising hell upon the untouched peace that Vena had acquired since it's birth. What had caused this large scale disaster?
all was caused in the name of order and 'justice'.
