The world is divided into two groups of people: those who are born, live and die, they are the mortals; and those who are born, live and don't expect to die anytime soon, they are the immortals.
The immortals have formed secret communities all over the world. The City of Survival is one of the places that's home to such an immortal community. That's where David, Gabriella, Seiko, Aalam and Sidar spent the first two hundred years of their long life. Until the life they have known in their little immortal city is no longer enough for them.
So they leave the City and enrol at a university of mortals. The mortal life is much different than the life they have known for two hundred years. At the university of Goldtown, they will be loved and hated, get to know the world and themselves.
But they aren't there only to live like mortals. They were secretly sent out, because they are part of a plan even they don't know about, a plan to suppress an increasing group of immortals who wish to no longer hide from mortals. They call themselves Purists, and they believe that the earth should be purified from the domination of mortals. They plan to destroy the mortal world, and from its ashes build a world of Immortals.
Seiko, Gabriella, David, Sidar and Aalam will find themselves in the middle of silent preparations of a war. A war that will be declared by the Purists, against all mortals and immortals who choose to stand against it. Unless it is stopped before it begins.
