Replying...
Intro. In this world there are only a few people who have one thing in common, surviving the 3rd day. Those remaining in the city have to find shelter or become stronger before that "3rd day" arrives. On that third day a portal will open in the sky of halos and monsters will descend with them, the rest will have to fight or flee...although, the best option is to fight, since no matter where or what you do, those monsters will find you and kill you. In this world, people are what they eat, literally. (You can choose who you are, traits, characteristics, etc.)
