explaining the world!!

This planet is called Aurora, and at first, only people lived here, until a huge meteor crashed, and effected the 50% of the population. There's a 20-year-old war that humans started from pure hatred towards the Effecteds (the people the meteorite effeted) and a team wants to end this war that's why the name of the series is "All We Want Is Peace". I hope my community is not going to be toxic, and i hope this'll be a liked story..
