Astrid, Raiden, The Twins and Dagur. 

Once the four arrived back at Berk they all quickly helped the Chief get prepared for Dagur's Visit. Astrid and Raiden thought it was a little strange that Dagur was coming a bit early and thought he must be up to something. While the Chief was giving Dagur a tour around the island as always, Berk got attacked by a swarm of invisible acid spitting monsters. Astrid and Raiden naturally assumed it was a new race of dragon. Then suddenly a storm appeared over Berk. Raiden used his psychic ability to read the mind of all living things in the area, blocking out the thoughts of the humans and focusing on the minds of the dragons. With this he was able to sense the camouflaged dragons. He then used his DNA manipulation on all the vikings in the village, giving them the ability to see heat signatures like a snake. Before Astrid and the others could do anything, Dagur stepped forward and sighed, he then said,

"I have only been here for ten minutes and already I've gotta save your asses. Where would you be if we didn't have this treaty? You're just lucky I am only deranged and not completely dishonorable."

With that Dagur casted a immobilization spell. Then used his Dragon Mimicry to copy the powers of a Skrill and got rid of the storm. He then turned to the chief and siad,

"Should we head to the dragon arena and have some target practice or would you rather kill them now?"
