The battle between Tyson and Rick began when the two were just infants and it got heated, as they grew elder.
Tyson was never good with fighting and his best gift was using his mind, while on the other hand Rick is the polar opposite.
When Tyson went to the knight Academy he was over shadowed by the Hero Luke Evester, so he didn't get the chance to recruit anyone under him and Rick was the cream of the Academy, as the only competition was the fool of the Evester family Leo whom he beat back to back.
Knowing that he could never out match his brother in a physical battle, Tyson started to gather support from nobles who focused on diplomatic issues of the Empire.
Tyson was able to be nominated as the temporary Crown Prince. Rick didn't stand still, as he gathered support from all the Noble family that were renowned for their fighting skills, including the Hero family.
