Dagur paced in his throne room. "Are you sure this is the best idea, Sir?" Vorg asked him. Dagur shot the viking an irate look, "Of course, I'm sure! I have to know dragons and that means I need to hunt them." he explained. The older viking, silently, shook his head, "Whatever you say, Sir." "No kidding there. Set a course for Dragon Island, Vorg."
The ships docked at the island and Dagur disembarked with more weapons than he should have been able to carry. "Do you know when you'll be finished?" Vorg inquired. "Not sure. If I kill all the dragons, I guess I'll have to go to another island. So, sometime before that."
Dagur made a spot to rest with some different woods. "Now, who's going to be my first hunt?" he asked no one in particular. Searching the island, he found a Gronckle. He charged and hit it with a club. The second time he rose his weapon to hit it, the dragon caught it in its fangs. The Gronckle threw both weapon and viking into a tree. Invigorated, Dagur climbed the tree and tackled the dragon. Putting it in the Berserker chold hold, he stabbed its neck. The reptile moaned, pitifully, and Dagur finished the deed with his sword.
"Well, that was fun. I might need some antidote later, though." he realized. He looked around and found some different herbs. Combining them in a large pot, he looked at them, "Guess there's only one way to find out if this works." he laughed, "Who's next? Oh dragon." he called out, in a sing-song voice, "Come out, come out wherever you are." he called and continued his hunt. Next, he found a Deadly Nadder. Crouching low, he threw a spear into the dragon's side. The Nadder roared in pain and shot a spine into his right thigh. Dagur yelled out and removed the spine just in time to roll out of the way of a magnesium blast.
"Ooh. Upset are we?" he asked. Dagur grabbed an ax and blocked several more blasts. "And it's out." he thought, knowing when the dragon had exceeded its shot limit. He threw his ax at the dragon's neck and it sunk in. The Deadly Nadder fell to the ground with a thud. "Not so tough now, huh?" he inquired, with his speech slurring due to the spine's poison. He slumped against a tree trunk and staggered to his base. He lapped up the, premade, liquid and was relieved that he had remembered the recipe, correctly.
"What's next? Right. A Monstrous Nightmare. There's got to be one around here somewhere." The young chief crawled and rolled throughout the forest. Rustling caught his attention and he stopped. Peeking through some bushes, he saw a lake and a Monstrous Nightmare drinking, peacefully.
Dagur readied his bow and aimed it at the creature. The dragon had smelled him and moved, last second, to avoid the arrow. The Berserker growled in frustration and aimed again. The dragon flew into the sky and shot fire at the viking. Dagur, narrowly, avoided being hit, climbing a tree to gain some height.
Hidden by the tree's foliage, he shot down the reptile. The dragon crashed down to the forest floor with a roar. Using gravity for momentum, Dagur leapt from the tree and brought down his sword on the dragon's neck. "This'll make a great trophy." he said, excitedly, "Watch out, dragons. There's a new predator now." he laughed and proceeded to remove the Nightmare's head.
