Dragon's Edge

Dragon's Edge is the temporary base for the Dragon Riders. It's located northeast of Berk, a 34-hour dragon flight away. The island is quite rocky and mostly flat. Three large mountains stand in the north, one of which is a volcano, while the rest is covered in forest. It boasts rich vegetation. Guard towers and balistae line the edges of the island for protection. Each Dragon Rider has built their own hut according to their preferences, all connected by bridges and ziplines.

Hiccup's Hut : There is a forge and a mill, the walls are hung with Toothless's prosthetic limbs.

Astrid's Hut : More like a fortress than a hut, and also has a watchtower.

Fishlegs' Hut : Located near the ocean, he built himself a house and a rock garden, as well as a pond where he meditates with his Sausage. He also has a botanical garden with plants.

Twins' Cabin (Tuffnut (boy) and Ruffnut (girl) : near their cabin they dug a boar pit where they spend their free time with each other or with Snotlout and Chicken Little (Chick Little is Tuffnut's chicken)

Snotlout's Hut : It is located higher than all the others except for Headquarters, and there is a barrel of water next to it.

All the huts are connected by bridges and stairs with a large hut in the center of the island. Headquarters is the gathering place for all riders. There is also a telescope near the headquarters for observing the island.
The island has a closed arena for dragon training. The island is home not only to dragons, but also to chickens and boars.

The main characters are: Snotlout with the "Horrible Beast" dragon named Hookfang; Astrid with the "Evil Nadder" dragon named Stormfly; Fishlegs with the "Grommel" dragon named Sausage; the twins with the "Prestegola" dragon named Bars and Vepr; and Hiccup with the "Night Fury" dragon named Toothless.
