There are many different ideas on how the world may end but obviously only one can be correct . Surprisingly only a small few people guessed right . It all started off with a virus . At first people were getting ill but then more of them died due to being affected . Not long after that, different variants arrived . Some would get back up after death and attack others , the ones that were still alive . While other victims would just die or just carry it and infect others . The lucky few , an extremely small amount of the original population, seemed to be immune .
