Viggo's Savior

"When Johann and Krogan left me for dead, a Monstrous Nightmare saved me. I spent my whole life hunting dragons, killing them. And I've come to repect them as equals."

- Viggo in "Triple Cross"

Home Cave-in
This Monstrous Nightmare lived on an unnamed island that formerly held a Dragon Hunter camp within a cave system there. It lived in the caves. One day Johann, Viggo, Krogan, and some Dragon Hunters arrived to find a Dragon Eye lens that Viggo though might be there. After failing to find the lens, Johann orders the Dragon Flyers to fire on the cave to collapse it, with Viggo still inside. Trapped, Viggo turns and is confronted with this Monstrous Nightmare, also trapped inside.

Later, Viggo manages to get Hiccup to come to the island and take him away. He reveals that because of this Nightmare, he was saved and developed a new and better outlook on Dragonkind. It is not stated where the Nightmare went after saving Viggo.
