Thank you everyone for the feedback and for the warm welcomes to the fanfic community. I do look forward to contributing more stories in the near and distant future.

I am aware that Cera's sisters are usually presumed to have perished, but I always found myself wondering,
"Well, what if they did live?" I was always intrigued by their mysterious disappearance after the first film, and the lack of true clarity regarding their fate is precisely what made me want to know more about them.
I had earlier mentioned to Owls that he inadvertently helped inspire this story. It was from a conversation him and I had about a couple months ago where the topic of Cera's sisters came up. They were already characters I wished we could've known more about, and so I probably would've written them into one of my stories eventually. Still, it was shortly after that conversation when the ideas for this particular story formed in my head and I began writing it.
More specifically, I'd wondered what the sisters' personalities might've been like, whether or not they were similar to Cera, and Owls said he thought they were probably all rambunctious threehorns. That gave me the idea to characterize the sisters as being energetic and hot-headed. Basically, what Cera herself was like before her character development throughout the first film. It then led to me writing the story around the idea that Cera is forced to confront what she used to be like.
Regarding the chapter breaks, it's always been my personal preference to divide my stories into chapters, even for smaller stories, and I often do prefer shorter chapters in general. Although I will acknowledge that a few of my chapters here may have been a bit too short, as well as what Owls said in that the second half felt a bit rushed. In the future, I will aim to make my chapters at least 1k each.
The only thing that felt dangling about this story was that Shanda's story felt like it was left hanging considering that she was the first of Cera's siblings to find out. The story abruptly shifts from her to Pyra after the rest of them discover the truth, and we never got closure of the aftermath of her role in being unintentionally responsible for Cera's attack on Pyra.
Shanda wasn't actually responsible for that, as it was a coincidence when Nova and Pyra later showed up in the grove to discover the secret for themselves. Although come to think of it, Shanda probably
should have been at some level responsible for setting that into motion, even if she chose to keep it a secret initially. I think narratively that would have made more sense. Likewise, you're right, it would've been nice to see how Shanda had felt about things after the fight. Perhaps I may expand on that sometime in a "v2" rewrite of the story.
the three threehorn (was that deliberate)
Nah, that wasn't deliberate, at least not on my end. The reason I picked three sisters for this story is just because that's how many of them we saw in the opening scenes of LBT 1.
@Anagnos @rhombus: I would like to ask for clarification on what you mean regarding how you would've liked more description in the narrative. You mentioned describing the characters better, which I would like to improve on, but is there anything else you felt could've been better fleshed out?
Lastly, for anyone who might be wondering, this hasn't yet been uploaded to Fanfiction.net, but I plan to do so eventually.
