Thing you need to know about this story are
1) Nothing will change in the movie except for the fact that important people would not die and the story wouldn't be tragic and it is due to the fact that the movie was made in a way that a situation will not only leave a clue about a coming one but also lead to the coming situation so the situations can't be averted but will be eradicated
2) I'm collecting Davina from Kol and it's the easy way or the hard way
3) The MC deals with the water element and swordsmanship and I figured out the ones with spectacular water abilities are those form the movie Alchemy of souls so I'm using that as our MC extra abilities
4) I find the final season to tragic so the hallow will be dying at the fourth season and the family wouldn't be splitted
5) We would have a little problem with the English
