Prologue: Prelude to Unknown

"If I could give you another chance to change the past will you take it?"//
"Yes."// The future is never set in stone. That goes with time, one small change can either lead to a great difference or a bigger tragedy - No one ever knows unless they face these changes head on and basically they are the one whom created that little ripple against time and fate, unknowingly.
