Total, complete, utter randomness...
When an orphan boy turned 1, a father sent his little baby son away to safety as the world was shaken to its foundations
When a little boy met two others who would become his best friends for the rest of his life, a little girl fell asleep while staying up to wait for her father. On her 5th birthday.
When that same boy went home to live with his new friends, that same little girl received a present from the late-arriving father, a deck that would end up sealing her fate.
When the little girl hurt another with her powers and got hit by her father as a result, two young, ambitious business-people fell in love and got married.
When the 3 boys turned 10, and the little girl became uncontrollable, twins were born to this young, ambitious couple.
When the twins were 3 years old and one of them mysteriously collapsed, the gang of 3 became 4, and vowed to protect their homeland together.
A year later, when the twins recovered, the little girl, now not so little, got sent away to boarding school.
When teamwork proved to be difficult for the fourth boy, and their friendship started fraying, the girl ran away from school.
And when the team split up as a result, the girl ended up running away from her home, upon discovering what she regarded as betrayal.
Even then, when all of these people were strangers, their lives were all connected.
