Slow down. One question at a time. Yes, we're from Berk. It's a little Viking village about twelve days north of Hopeless. Alpha means he's the undisputed leader of all the dragons on Berk and some of the nearby islands. And, yes, those are out real names. In my case, hideous names are supposed to ward off gnomes and trolls, and in his it's because he has retractable teeth.

[Toothless is, thankfully, somewhat used to hyperactive kids thanks to Fishlegs' cousins. He's sniffs at Bart's hand, and bumps his head against it, giving the boy permission to touch him. Although, he reserve the right to rescind that permission if Bart starts climbing all over him and tugging at his earflaps.]
