Players play as a Viking student arriving at the wrong time as the Berk Docks are being attacked by Grimmel's Warlords.

The player also learns to hatch a dragon egg in the hatchery and can choose a second dragon from the four basic species, as well as the Sand Wraith, Flightmare, Rumblehorn, or Shockjaw. The player then has the option of playing four different branches of quests as part of an introductory expansion in order to learn how to play mini-games, care for their dragons, and other functions. Hiccup then instructs the player in dragon flying, and when finished, the player and the Dragon Riders fly through the opening in the caldera in which the School of Dragons is situated, with a video montage introducing many of the NPCs the player will encounter in the game. The player helps Hiccup construct a signal fire, allowing Toothless to find them, followed by Astrid and Stormfly. Hiccup and the player find the cave exit but also find a crate of dragon eggs in the process.

The newly bonded dragon is aged up by Hiccup and the player learns to get their dragon to shoot fire at a cave in so they can escape. The player unlocks one cage and bonds with the player's choice of the four basic dragon species.

The player and Hiccup unlock trapped dragons, while the player learns the controls. The new player finds themselves in a cave with Hiccup that the Dragon Hunters had recently been hiding out in. School of Dragons Official Trailer 2022 Update
