In fact he is there because he is investigating some corrupt acts that are also affecting his state (country) and he suspects the royal family it end prety well... Luna ends up falling for him, snd of course Fortis liked Luna from the very beginning but he wants to break the engagement thinking he is no good and he is also afraid that when she grows up she will keave him for someont else beause she is bound to become a beauty and a bunch of and going to be after her ... to mar the story short Luna goes after him they have A TOTALLY SWEET MOMENT Fortis blushes A LOOOOOOT!! ( keep in mind this happens on the street ╮( ̄▽ ̄)╭) haha they confess to each other and get engaged again, Fortis says to her that she better doesn't regrets it after becuase he is not letting her go (づ ̄ ³ ̄)づ
