The New Guardian- Jelsa

Queen Elsa of Arendelle, daughter of Agnarr and Iduna, formerly.
Queen Elsa, Snow Queen, daughter of Man in Moon, currently.

Queen Elsa is still ruling her own party. After becoming immortal she has a sort of free style life. She is soon wanting to have her own kingdom to rule, down in the spirit world. But when Elsa's father chooses her to become a guardian and leader of the new guardian group to defeat Pitch once and for all, things have to be put to the side.

Pitch is back and stronger than before, and only with the help of a little wizardry to make sure nothing goes wrong. Elsa is now having to deal with Pitch and the conflict of having the love of her life by her side at all times and the more conflict of having Pitch as a brother.

I mean what's the worse that can happen? Right?
