(This takes place at the tail end/right after RTTE)
A trading ship comes to berk filled with supplies and an exhausted crew. The sailors claim that there is something cursed in the hold below. All because DARYL JUST HAD TO BRING A BANANNA WITH. Causing all sorts of trouble. Misplaced objects, Locked containers and cages open, things moving on their own, and for the last 2 days, terrible noises at night. They hadn't gotten a wink of sleep.
The vikings carefully unpacked the ship's supplies till one small room in the hold was left. loud scuttling noises could be heard on the other side. The door was slowly opened and 2 golden orbs stared back. Attached to these eyes was a small, black, dragon. With 2 enormous, curved, golden, horns. Hunched over a basket of fish. The small dragon squeaked and bolted past the vikings, jumped out of the hold and ran right into stoick.
Hiccup and fishlegs are ecstatic over the new dragon, Stoick is not. It became quickly evident that this new dragon was the devil spawn of loki himself. With the intelligence of a human child to boot. It could open any container, pick locks, escape any cage. After 2 days of hell being wreaked on the haddock house Stoick was done. The twins BEGGED to take the new dragon and hiccup was planning on letting them try. But stoick said no and voluntold fishlegs for the job. So the dragon was moved to Fishleg's house. Then astrid's, then snotlout's, and finally only the twins were left. Much to their joy as they had been BEGGING to take care of it the entire time. To everyone's surprise but hiccups, it worked. Only the twins could keep up the the insanity of the new dragon. The twins were also the first ones to figure out that the new dragon was in fact, a baby. The new baby dragon was dubbed Loki's gift and put into the sharp class.
A few days go by when things start to go wrong on berk. Machines falling apart, buildings collapsing, and worse. The twins always were at the scene with Loki's gift. So naturally it took little to no time for everyone to blame them. Even hiccup couldn't deny how suspicious it was that they were always at the scene. It took Astrid vouching for them to get everyone to back off, at least for a few days. Hiccup had a plan, because he had everyone follow the twins all day. They only saw one thing, a long black dragon tail with golden spikes. A trap is planned, but before they could enact it the twins' house collapses. A tall, pitch black, dragon stands atop the rubble. It's shimmering, golden, spikes, teeth, and claws shimmering in the moonlight. With to massive golden "devil" horns adorning its head. Barf and belch attack and a dragon fight breaks out, only being broken up after stormfly and toothless joined in. Meanwhile snotlout, hookfang, fishlegs, and meatlug are desperately trying to unearth the twins from the rubble. They are fine by the way, they encased their beds in a cage that day. Loki's gift however was not, with a badly broken leg. Hearing the pained squeak that loki's gift let out at being picked up the other dragon went into a fury. Only stopping when the baby squeaked angerly at it. An exchange of sounds and the adult, calmed, slowly approached the baby. Clearly showing no malice, Tuffnut reluctantly gives Loki's gift to the big dragon.
The towering demon instantly became a doting mother and extremely thankful once the babies health was assured. Once reunited it was clear that the Mother dragon had done all these things to take revenge on the twins for "stealing" her baby. Amends are made and the Devilish Dervish is named. Loki's gift has lived on berk ever since and adores tuffnut, to the point of occasionally kidnapping him. Much to the ire of Barf and Belch.
