Timeline: A Tale of Altered History

Robert had never used his father's invention for personal gain, but saving the life of his brother was a risk he just had to take. Unfortunately, no matter how much preparation is involved, things can never go as planned when you're playing with the very fabric of the space-time continuum. If Robert succeeds, he will rob the family who is plotting to kill his brother of their power from the moment they acquired it, deep in the past. But if he fails, it could be more than just his brother's life that is in jeopardy. Either way, he will certainly alter history and create a new timeline of events, which in turn will radically change the life he has always known. But will there be a price to pay for his actions? Consequences for "playing God?" Perhaps most importantly, if things go wrong, could any of the damage ever be fixed?
