[IM] was short for a deadly virus called Imitation Mutation that killed off 80% of the world's population in 2038 during the first few weeks. When the outbreak of the virus happened, countries border closed, safe zones and quarantine areas were established but they still couldn't manage to curb the virus. The virus [IM] was able to completely mutate and take control over a human's body. Turning them cannibalistic and brain dead along with making humans into monsters with insane strengths and powers that were created from the host's fears. These monsters were called mutates. However, the possibilities of [IM] mutating a human was 35%, which is a lower percentage of humans dying a few hours after contracting the disease. 0.4% of mutates can turn out to be a special case where the hosts still have complete control of themselves even after receiving the effects of the mutation. Zephyr was a special case of mutates that was being kept as a prisoner along with many others. To protect himself, he hid himself away in the void, hopelessly waiting for the day to break free. Finding himself a new 'home' to stay in, he attempts to neglect his past and fixate on the present. However, it seems like fate bears a strong hatred for Zephyr. Revenge, disgust and death followed him wherever he went.
