Galen is one of the highest ranking army members, the other being Elena, Max's mother. It is possible that the reason he is so high ranked is because of his friendship with King Raybrandt, Monica's father. If the player completes the Georama for Heim Rada 100%, Galen will present Monica with the Holy Daedalus Blade, the sword King Raybrandt left for her. Galen is one of the supervisors of Paznos, the army's ultimate weapon, and can be found there after Chapter 5.
