Fate (Ignis Scientia fanfic)

Long ago, the first king of Lucis made a deal with Shiva, the ice goddess. Every generation if a king of Lucis has a daughter, they are to take the place of Shiva. This was the deal in order for him to gain the power to summon her when needed. They will be given the power of ice, and when the time comes, they are to die and become the ice goddess. Princess Hoshi is Prince Noctis's baby sister, and King Regis's only daughter, every king of Lucis knew about the deal.

King Regis always promised to tell Hoshi about the power she's been given. But he never got the chance. But what will happen when she falls for an old friend? Will she die before she could tell him how she feels? Or will she embrace her role as a future goddess and neglect HIS feelings for her?

(This will have a certain phrase from The Princess Bride in it...those who have watched the movie will know it when they read it. Also, I do not own the characters or the fanart.)
