There are not only the Grimborns-brothers. No. They have also a little sister. She is 15 years old and loves dragons. Her name is Zarinia!

Zarinia has no particularly good ratio to their brothers. Because they are Dragon hunters. And it prevents nothing. Every day she secretly sneaks to a few Dragoncages and visited their favorite Dragon: a Sun Fury lady, with the name Sunshine; a changewing called Phantom; Firewing, the monstrous nightmare; the triplestrike thorn; Metalscales a razorwhip and spikeeye the deadly Nadder.

She loves "their Dragons", but she's afraidof the day Viggo sold her dragons. Because there are actually his dragons!

What should she do? Exactly this question Zarinia asked herself again that evening. Simply take the Dragons? No, she couldn't do that to her brothers. Even if they wouldn't even know if she were suddenly gone. She decided to wait.

Anyway, it was time for dinner. So she set out on the way.

But after dinner, a surprise wait for her. The Dragon Riders, whom Zarinia totaly admired in secret, had destroyed Viggos plans agin. And the head of the Dragon Hunters was finally tired of that! He had a new plan. Because he knew that the Dragon Riders had a spy in the ranks of the Dragon Hunter, Viggo wanted to send one into their ranks as well.  And that shouldbe no one else as ...his sister ZARINIA!

She is totally overwhelmed with the sudden task.

Zarinia: "How should I do that? And what if,  they expose me? And how should I get  on Dragons Edge?"

   Viggo: "Don't worry." The traitor will come to the island tomorrow and will see you in our Dungeon... She will tell the others and they will want to free you and your Dragons. Then you live among them and realize all their maneuvers. Every evening at sunset, you're going to the beach. One dayI'll send Ryker to you and he will kidnap you. So you come back to our island." 

Zarinia: "My dragons?"

Ryker: "We've  known for a long time that you sitnear to the dragons every day ."

Viggo: "You pass these Dragons of as yours. So Hiccup and the others even more confidence in you. You can take the six dragons you always care about. But if you refuse or betray us I will sell them ALL!"

Zarinia (something queasy to feel, but very happy that she glad the task with her dragons): "Of course, Viggo. When does it start?"

Viggo: "Now! Ryker brings you into the cave, where you will spend the next few days. Your dragons will be brought even there too."

And with these words, Viggo leaves the tent and Zarinia is taken away by Ryker and brought to a cave, in which are a bed, a table and a chair.
