The World of Frozen

So, who exactly in this world of ice, magic, spirits, kingdoms, and dear, royal sisters gets this power? And when in the timeline do they ascend?

Author Notes from Forcy, the OG author of this story: I cannot believe I never thought of adding a potential branch for this franchise in here before, but well, better late than never, I guess. I do have some ideas for what would come next in my own thread but I would rather catch up with writing a few more chapters of my other tales first so, if you want to start your own take of this in the meantime, then by all means, take a leap into the unknown and get started :D
