Your dragon is indigo blue Thermith!
"blue Thermith" by Chris S. Baily
Your dragon is indigo-blue Thermith. And you weren't looking for a nice, mild-mannered, easy-going blue, were you?
Because Thermith isn't one. Sometimes you think he Hatched on a mission. And that mission seems to be to excel as a blue – an unusually large one, bigger than several of the browns – without actually overstepping the limits of his colour. Thermith has tremendous respect for authority, and won't tolerate rulebreaking or troublemaking – even from you. Especially from you. And that means all the greens, and other blues, need to watch out, because Thermith's going to be keeping his beady eye on them!
If Thermith has a fault – besides his rather deferent behaviour towards more senior colours – it's that he has no sense of humour, at all. He won't understand most jokes, and react very poorly to being teased. But you'd never do that...would you?
