They are the sons of struggle. Fight for survival. The fight against those who have been enslaved by their own machines. Fights against those who came from other worlds, powerful and alien, inaccessible to human understanding.

And there is no return for them to Earth... and does it still exist, this Earth? And each of them is a Phoenix, for again and again it is reborn in the flames of war, hardened in the crucible of battles and ready to confront danger again...
