nightfury origins.
you know that schoolyard rhyme? yeah.
Skrill and whisper-death, sitting in a cave.
K-I-S-S-I-N-ROAAARRR!
...
First comes flying, then comes mating...
Then comes toothless in a dragon egg!
That's not all, that's not all
Toothless friendly with a Viking runt!
:The author was promptly crispy fried with lightning and then ground to a mere smear on the interior of a rock tunnel.:
Skrill: it uses lightning. It also LOOKS a lot like a night-fury.
Whispering death: death is in the name. The other option for death so far, the green/red death, is simply...too big
Nightfuries: "The unholy offspring of lightning and death".
