Just as note - I haven't read any of the Pantala arc books yet (we had only first book of second arc published here not long ago), so all my knowledge I took from Wiki.

Here's my attempt on making something reasonable of dragon having two pairs of wings growing one just after another.
I always found it quite a waste of potential that when drawing different species people mostly just change head/wings shape and maybe add some features like spikes/barbs, and basically that's all. And with Pantala dragons it's more than obvious that their way of evolution was completely different than Phyrria ones - number of limbs alone would speak for it. The description is still quite unclear (wings that are supposed to be insect-like, but still have digits), but I'm quite used to no/unclear descriptions after my whole Temeraire series.
So I took a different route with this one, trying to use more feline/insect looks.

Anyway meet Nymph - she's a weaver and she enjoys her job. She likes to go out and sunbath, spreading her wings in the sun like butterflies and relax playing cat cradle. (I don't know if there are any hives with ground/cave-like entrances, but maybe it's just a servant's "gate" or something.)
