The Prime Knight (shortened to PK and called Avatar in Brazil) was chosen by the gods to establish balance in the world after it was thrown off by the forces of evil. The powers of evil continued to grow, and the gods soon realized that the mortal world was in peril. The gods summoned an elite group of knights from which they selected the very best warriors to become Prime Knights. Sieghart the Highlander had been training with the other Highlander Warriors when he caught the eyes of the gods, and having passed all of the trials presented to him, returned as the Prime Knight to save the world.
