So I've Got This Httyd Au Idea That I've Been Sitting On For Awhile Now, I Guess It Could Be Considered

So I've got this httyd au idea that I've been sitting on for awhile now, I guess it could be considered as a rewrite or something but I don't see it that way. Anyway here's some ideas for my Colourful Nights AU, I'm still working out the factors so it's not the best.

There's going to be more of my thoughts under the cut (aka the usual Hauntley rambling)

First and foremost, the idea to give Grimmel a night fury comes from this post on reddit

Before seeing this I had 100% planned to just... Not have Grimmel exist in the Colourful Nights au? I kind of hate his whole- thing?

I had the idea of Grimmel seeing what Drago did and deciding that where the man failed was not in trying to control dragons, but instead that he didn't try to control powerful dragons specifically. I know that Toothless is supposed to be an endling, but I think the idea of Grimmel slowly building his own dragon army but with dragons he considers powerful and having a few night furies is cool so. Maybe he kept a couple of night furies back during the mass fury hunts, because having them bend to his will makes him feel powerful? Or maybe he only had one. I'm not sure if I'll even keep it but I like the idea.

For my light fury design (I call her Clearscales), I liked the idea of her being a night fury with some sort of genetic mutation, and I'm not sure if I want to keep the disappearing act or not? I like it but I don't know if it would still work if I gave her darker scales, but also! Would I be able to call her Clearscales still? :( That's a very important part, because I've gotten attached to the name.

I also had an idea that relates back to a fact about the Dramillion titan in rtte, it has the ability to camouflage itself like a changewing because they're distantly related, implying that titans have access to traits the normal members of their species don't have.

So what if Toothless' lightning isn't an inherent night fury skill, but instead a trait of night fury titans? Maybe it's due to a possible distant relation with skrills? I always liked the idea that the "lightning" part of "Offspring of lightning and death" was because their blasts look somewhat like a the result of a lightning strike (at least in the 1st movie), but maybe it's also because a titan was witnessed doing this, and because the second and third movies imply that after the first transformation, the titans don't look any different from the normal members, people just assumed that it was something they could all do, and ontop of everything else, it led to a mass panic and hunt?

I'm all over the place and am in no way coherent, but that's my dumb little idea, if you're reading this I can't believe you actually read what I wrote, or scrolled down through it at least. Thank you :)
