18 years ago, a boy was born to one of the most powerful mutants in the world, and the leading doctor in genetics, Professor Charles Xavier and Dr. Moira McTaggert. David Charles McTaggert grew up with his mother on Muir Island while his father went back to New York to create what would later be known as Xavier's School for Gifted students.

As the boy grew, so did his jealousy at his father's inability to connect with him, whereas he was perfectly able to connect with his mutant students. Young David's powers came to light when he was 13, and with the powers came the boy's mental illness. In a fit of rage, the boy killed his mother, after learning the use of the Muir Island jets and how to get to his father.

With Moira dead, and Muir Island destroyed, the thirteen year old boy flew to New York, set on taking apart the entire mansion, along with its inhabitants, which included Jean Grey, Scott Summers, Ororo Munroe, Remy LeBeau, and Logan Howlet, along with younger students that Charles had started bringing into his school.

After a long a difficult battle that included X-Men and students alike, the boy was faced by an irate Jean Grey, who was prepared to use the full force of her powers to keep the boy from killing anyone in the mansion, however she was stopped by Charles.

With a smirk on his face, the boy killed his own father, however the strength that it took to kill Charles left David too weak to do much else. He left the mansion in ruins, but not before telling the X-Men that he would be back for them.

Currently, nearly five years after the death of their beloved Professor, the X-Men have reopened the mansion, keeping the superhero portion of it a secret even to the students. The Brotherhood has been formed by a blue skinned, redheaded morphing mutant named Mystique, and a precog named Destiny, after a prophecy shown to Destiny showed Mystique ruling the world as Homo-Superior. The only catch is the fact that David McTaggert was the brawn, while Mystique was the brain.

Where will you stand? Will you stand with the X-Men, who have pledged themselves to their students and the world that hates them? Or will you fight with the Brotherhood for David and Mystique's view of Homo Superior ruling supreme?

Sometimes, you must make a Sacrifice.
