What does "Mu" (武) in martial hero (武俠) mean? It is the power to enforce one's own sense of justice (俠). If that power extends beyond oneself, through others, and reaches the ends of the world, then that is the realm of the divine (神). What does a mere human need to ascend to godhood (入神)? Now begins the epic of Pi Wolryeo in search of that answer!
