It seems like the dragons are trained by this point, but the name still rolls off the tongue nicely.
In the third and likely final film in the series that started in 2010, the main character Hiccup (Jay Baruchel), an expert dragon trainer and rider is now chief of Berk. Since the events of the second picture, the island village where vikings reside has become a sort of safe haven for dragons. Because the people of Berk have become experts in handling dragons, thanks largely to Hiccup’s efforts in the past two movies, the dragons are able to live in relative peace.
However because of how many dragons are coming to the island for safety, the land is becoming overcrowded. This is on top of the fact that there are antagonistic forces who want to eliminate dragons, seeing them as a threat. In response, Hiccup decides to find the so called “Hidden World,” where dragons can live safely without being found.
