This is a Sci-Fi/Fantasy mash-up story, it's setting being in a parallel universe. I'll also use elements of Korean mythology and co.

'The Cult of Apocalypticism' is, in fact, an organisation of eschatologists (for those who don't know, Eschatology is a part of theology concerned with what are believed to be the final events of history, or the ultimate destiny of humanity)with special abilities that are more or less related to their zodiac sign.

The members of the 'Cult of Apocalypticism' are actually entire constellations who took the form of human beings (because there actually is a scientific theory that proves the fact that people are formed from star atoms or something like that) but of course, they don't know that. They are the last people of an ancient civilization, also known as Starseeds. 

It all begins when a sinister tower with a huge crystal on top of it appears apparently out of nowhere in the middle of a metropol. It seems that the crystal actually shelters the answer to all of their questions..
