Story is simple (at start, but as all other clans start participate it will go who knows where...)
Hampa made virtual bubble where Toriworld is (cute planet where every clan have their continent floating above core) It is guarded by moderators who are like demigods. Then rapture in bubble start in the unfinished sector and the strange alien things start to invade almost unstoppable. They are severing anchors that continents have with core and by doing that destroying the Toriworld and inhabitants. Clans will have to unite... No more spoilers.
