Though mutants have only existed for two short years, Charles Xavier believes that humans and mutants can share the planet in a peaceful co-existence. He has opened his home, creating the Xavier Haven for Gifted Individuals, to all mutants who need help or seek to better the world with patience and understanding, using violence as a last resort.

Impatient with the ignorance, fear and hatred of humans towards mutants, Erik Lensherr and his Acolytes broke away from the Haven and formed The Brotherhood of Mutants in order to pursue a dream of their own: Tolerance and acceptance now, not later. Convinced that only action will create change, they struggle to right the many injustices of the world.
