Dragons Race To The Edge S03E25-Maces and Talons-Part 1 mp4

The riders successfully rescue more dragons from the hunters, leaving Ryker with suspicions about Heather. Their group finally returns and meets the hunters' true leader, Ryker's younger brother Viggo Grimborn, who proposes a secret alliance with Heather in order to oust either Ryker or Dagur as possible traitors. Heather meets with the riders and informs them Viggo is after the Flightmare, but this proves to be a trap by Viggo to eliminate the riders and exposes Heather as a spy. Hiccup plans to use the Flightmare's mist to paralyze the hunters, but Viggo's advanced tactics allow him to escape with the Flightmare, Heather and Windshear as captives, leaving Hiccup to wonder about their dangerous new opponent.
