When he was young, because of all the wars in his country, he went insane with bloodlust. He didn't believe in any God, and this was worrying to Old Prussia. Old Prussia was his mentor, and he couldn't leave Prussia alone, as the sole representation of Prussia, without being sure he could handle it. So he taught him about God, and gave him the cross after his latest battle, in which he led his troops with the Blessing of God, as he had gone to a priest to inquire on wether or not the war was a good idea. Old Prussia was proud, and gifted him with the cross as a promise to do this before every battle, and to never forget about his God.

               And even now, years later....
                          Prussia has not forgotten....
