Daddy's Home! (Elsa/Pitch/Jack Frost FanFic)

Elsa has two sisters:
1.) Her younger sister, Anna
2.) Her twin sister, Fiona

Elsa has a magical Ice ability & Fiona has a magical Fire ability. Anna is the ordinary emo girl. At least.... she has been ever since her parents died and her sisters devoted their time to training together to use their magic.

King James, of Arendale, died in a ocean wreck along side his wife, The Queen, Helga... He thought. Now he is back, but appears to look a bit different. Plus, he is being called by a new name... Pitch! Pitch also has magic... Dark Magic. He's not enjoying that one very much. His current goal:
Step 1.) Get home to Arendale.
Step 2.) Reunite with his daughters, Fiona, Elsa, & Anna.
Anna is a sweet girl, he remembers. Fiona is, too, sweet, but a bit frightened by her fire powers, much like her twin, Elsa, is with her ice powers. But Pitch is determined to get home and help his girls. But whoever the "Pitch" before him was, he's pretty ticked. Guardians are after him. One specifically..... Jack Frost! Will he make it home to his girls in time? Or will he be too late to save them & Arendale?
