2167 AD is shown to be devastated by a powerful electromagnetic shockwave. This is caused by a nearby star, Hydrus Beta, 20 light-years away, going supernova. The series itself is set 189 years later, in the year 2356 AD. Civilization has been rebuilt with humanity having united together to face the coming of the second shockwave of the supernova. The second shockwave, unlike the first, is to contain a great deal of matter composed of the remnants of the star itself.
