|— Dagur [src]|
Dagur has been introduced in SoD with the Expansion pack Rise of Stormheart.
With his experience on the "evil side" he can foresee the enemy's moves. [src]
In the game Edit
Dagur appears in the very first quest of the expansion, Rumble in the Edge, helping the player with a wild Triple Stryke. He understand that the attack is part of a bigger plan (What's Going On?), and that the Triple Stryke didn't act naturally, so he suggest to investigate the cause of her behavior (Grimora?).
He then helps the player investigate in Auction Island, and recover a supposedly stolen boat in Johann's Secret Mission, helps again in the battle against wild dragons in Prepare For the Worst and in the attack to Stormheart's ship in Taking the Offensive. In this quest too, the player will save him from the wild Triple Stryke.
As this expansion is set after the facts of Season 6 of Dragons: Race to the Edge, Dagur and Mala are now married in game.
Dagur and Mala are trapped inside Stormheart's ship in Dagur in Distress, and require of the player's help to break free. He then confirms support from the Berserkers against Stormheart in The Scourge of Stormheart.
He holds a grudge against Stormheart, and he's ready to attack her when the Riders discover she took Auction Island (The New Auction Island), but Hiccup prefer to retreat.
Dagur and Mala appear only in the quest The Problem With Warlords, where they are fighting against the warlords at Impossible Island.
Dagur's appearance in SoD is due to his desire to visit her sister [src]. And he says he loves his "weird little sister", referring to her interest as chemist [src]. It seems that Heather has some influence on his brother, so that he promises her to behave when going on dangerous missions with the player [src].
His Dragons Edit
While Shattermaster is only mentioned [src], Sleuther is seen in game. Dagur states that he's ready to use his axe against anyone that hurts his dragon [src]. He's also happy to teach Slether "new tricks" like how to rig a ship, thinking any kind of experience can be useful. [src]
