It's the end of the road (skies?) for Hiccup and Toothless.

The filmmakers behind "How to Train Your Dragon 3" have revealed new details about the final installment of Dreamworks' mega hit animated franchise.

"We thought about it for a long time and came up with what we think is a bittersweet way to say goodbye to these characters, but the right way,” director Dean DeBlois told Entertainment Weekly.

Not only will "How to Train Your Dragon: The Hidden World" conclude the film trilogy, it will also conclude the popular television spinoffs.

“You will understand why Hiccup says, as you heard in the trailer, ‘There were dragons when I was a boy.’ And by the end of this film, you’ll have answered the question of what could have happened to them.”

The movies have followed Hiccup (voiced by Jay Baruchel) as he bridged the divide between humans and dragons, largely through his own relationship with his dragon friend Toothless. Along the way, he lost his father Stoick the Vast (Gerard Butler), found his estranged mother Valka (Cate Blanchett), and romanced Viking villager Astrid (America Ferrera).

"The Hidden World" brings back Stoick in flashbacks, and in one, he tells a toddler Hiccup about a secret home of dragons hidden by a great waterfall somewhere. Now grown up, Hiccup wants to find that safe place, especially with a villainous dragon trapper on the prowl.

"How to Train Your Dragon 3" opens in theaters March 1, 2019.
