Grandson of Leon and son of George Silverberg, Caesar was brought up along with his brother Albert to become a military strategist. While he didn't work hard in his studies, at times he showed great potential, by helping people out with business strategies. After meeting Apple, who was writing Mathiu's biography, he became interested in Mathiu and Shu's philosophy.
While travelling with her, he helped the Fire Bringer to win their war against the Destroyers led by Luc, acting as the main strategist, and masterminding all their military victories. However, he continues travelling the world after seeing his brother Albert's superior knowledge.
