During the early days of RBR, Doctor Robotnik created the Chemical Plant Zone on a previously green area of Mobius, destroying all nature there and making the sheep homeless. In revenge, Sol joined The Flock, a team of Freedom Fighters dedicated to ridding their home of Robotnik's influence, and became one of their leaders. At some point in time, Nutzan Bolt took over the running of the Zone and convinced Sol that the pair of them could build "a better Chemical Plant". The split between Sol and Sab was a tearful one, but Sol left anyway, believing it to be their only chance.
