Wowowowow. I'm so lucky I found this gem of a story. Really was invested through the whole thing. Just. Wow. I don't usually finish stories that go through a very convoluted plot but DAAAMN. this was an awesome ride. Also read it on one sitting. Litterally took me all night. Worth it.

Hi, I just wanted to thank you for this wonderful story. I had a terrible week and your story lightened my mood. Thanks for that! I usually don't write comments, especially because English isn't my main language.

Well, there were definitely things about it that I liked. I liked the time travel aspect of the story, the romance between Hiccup and Elsa was cute, and the OCs weren’t terrible. Plus, you left out Olaf, who I absolutely detest, so good job with that. I do, however, have two gripes. First, rampant spelling errors. This story seriously needed a proofreader. I lost track of how many times you used “loose” instead of “lose,” which is one of my biggest pet peeves. Second, while the OCs weren’t terrible, there were entirely too many of them. Since this is a crossover, you’re essentially trying to fit the cast of two unrelated series into a single story, and on top of that adding a SHITLOAD of new people for us to keep track of. I’d like to emphasize, though, that these are my first impressions upon finishing your mostly excellent story, and it’s just a policy of mine to make some suggestions in all of my reviews.

Great story. Only feedback was that there felt like two many characters for my poor tiny brain to handle. I could keep anyone straight in the first could chapters of the second part.

Love your personality

So sweet please give elsa her own dragon maybe a snow wraith. Please please please

Hi!
I'm in first third of this story and think that it's time for I let you know my first impresion of this story :D I really like this story. And I appraiceted that you think about, how people would react in certain circumstances.

PS: the fact that you using old norse names is awesome :D

Wow, it's done! I just had the impression that Hiccup's friends sort of disappeared. Whoa! So that's how Elsa had her powers inherited. It was because of Isis !
All the paradoxes and the way you explained everything was fantastic !
Hehe I can't believe I guessed it somehow.
Thank you for posting this marvellous story.
Do keep writing !

How sad that Isis is gone... I can't believe it! Ophelia is so not going back, in fact after all of this I would be surprised if she went to Arendelle. She most likely stay with Cal. He's had a really hard life. He's literally alone after loosing all his family. Ophelia is what he has... He also has Elsa, but he'll need to work things out more with Hiccup I think.
So much has happened, that I believe those two would want a new start... Who knows? Maybe she'll be responsible for the beginning of Arendelle.
And what sad story for Astrid. It would be nice if she remained in the future for a new beginning.

I never saw that coming... I mean Ull. Wow, that's so messed up. But cool ! They know how to time travel with a dragon no less.

Haha really? She likes Calder, doesn't she? Oh joy, I wonder what Elsa and Hiccup will say to that. The irony of life...
Oops, Ophelia doesn't want to go back home... M'y my, she has a rough path ahead. If she's the next chief it won't be pretty if she were to be associated with Unn's son.
Yeah and her parents will find her somehow ? And what of Astrid ? Hopefully she'll get a happy ending for herself after accepting that her relationship with Hiccup was not meant to last.

No wonder Elsa felt that way! Cool, but Calder is having a hard time... Hmmm am I crazy or think there's more awkwardness between Calder and Ophelia ? Calder should be the eldest and followed by Elsa's niece. I would have thought they'd be on friendlier terms.

I really appreciate you do a separate set with M rated scenes. As sometimes stories begin with a different rating and without warning switch. Not that I would read them, but I'd just skip it or drop the story altogether.
Great! I want to see more of Berk, though I feel Astrid is OOC. I expected her to begin a new life... But Who knows I'd she meets someone if she goes back.

Gothi's idea is very creative... They're Just doing it to keep her safe. But it is sad. They should keep her busy.

I was just laughing so hard in this chapter. Hahaha they're close to a food fight one of these days. As for the ice powers... Yeah, I don't think Hiccup would have a problem with that
Cool! Ophelia is having a blast. Not that I expected otherwise.
