We`re in the year 2042.
Minecraftia just experienced a Nuclear War, which surpassed all estimations. A great part of the population died, but there were survivors. To be precise: two types of survivors. People were waiting in bunkers until the bombings stopped. Afterwards many stepped out. Bad idea.
The Fallout coming with the rain slowly mutated their DNA. They might have survived, but they are no real humans anymore...
This creature is highly aggressive and will even attack members of it`s species. They hunt at night, as their huge eyes see excellent in the dark, but are blended by sunlight.
So well, I hope you like this different kind of survivor ^^
