Ryu narrating:
*We see a book with a Night Fury symbol on the front cover as soft score is playing*
"You wanna hear a story about dragons?" the voice asks the audience.
"Everybody's got a favorite, right? Attacking villagers, threatening fair maidens, hoarding piles of gold" he lists off.
*On the 1st page we see a Night Fury, a Monstrous Nightmare, a Deadly Nadder and a Hideous Zippleback. On the 2nd page, we see Monstrous Nightmares approaching a village (aka Berk) and others spewing their fire*
"Those stories about dragons that terrorized the Vikings in the northern seas?" he asks.
*On the 3rd page we see Vikings on a cliff defending themselves and fighting a Monstrous Nightmare, a Deadly Nadder, a Hideous Zippleback and some Gronckles.
"Yeah! Yeah, those are some of my ABSOLUTE favorites." he admits.
*On the 4th page, we see Hiccup looking scared at Toothless on a rock behind him that's staring him down*
"Of course, those stories are just stories, right?" he wonders.
*As the pages continue to flip through the book, we see Hiccup looking away while holding out his hand with Toothless a few centimeters (or inches for you Americans) away from his hand*
"Dragons don't really exist." he begins.
*Below on the same page, we see Hiccup on Toothless flying away from the Red Death chasing them*
"They're just myths and legends, you know stuff to scare kids." he continues.
*The page flipped as we see Hiccup on Toothless flying to the setting sun above the waters*
"But I... I've got a dragon story you have never heard before." he informs them.
*And at the last page, we see the archipelago map from Hiccup*
"A story that really happened and this story?" the voice chuckles
*We go away from the book and into space*
"This is my absolute favorite, because this story is mine" he finishes
*We see a comet flying through space as it races close to earth, but doesn't hit it and the title card comes on screen*
