Love this topic choice! I've always had a strange variety of dragons in my lair, and I enjoy having different flights work into my lore, especially since I've moved a few times myself (and have incorporated each of the flights into the environment the clan lives in!)
I'm in a pretty good location to have a good variety of flights, and it also helps that my clan isn't set in one specific place, and we have two smaller clan locations, along with a large group of wanderers / nomads, meaning that dragons who are more interested in water are able to live near it on either side, regardless of if they prefer salt or freshwater. Wind dragons are naturally at home, and Nature dragons have adapted easily as it's a pretty similar environment, in my mind at least.
Now, for specific dragons:
First is Grizma; she's a Plague dragon, the opposite of the flight we just moved from--incidentally, she's the cause of half of the clan's population being decimated, as well as our move from Nature to Wind. However, I like to think that Plague dragons are very adaptable, as sickness seeks to spread everywhere--in Wind, I think she flourishes, actually! (Airborne illnesses, anyone?)
I haven't written her lore down yet (man, I need to) but I think of her as an agent of Plaguebringer, sent to spread her particular brand of plague across Sornieth. While the clan naturally suspects she had something to do with the sickness that wiped out half the clan, without proof, she could not be punished, and she continues to live within the clan under the guise of an apothecary, specializing in herbal "remedies" and various potions and poisons.
As a Plague dragon, she made the clan anxious (as we were still in Nature when she joined) and everyone kind of held her at arm's length, not that she seemed to mind. She lives on the ground below the floating gardens of the clan, as flying isn't her strong suit.
Luyten here is actually a Wind dragon, but I bring her into this particular post because for the longest time, we lived anywhere but in Wind. I got her when I was in my first flight (Arcane), and I like to think of her as the beginning of my actual clan. In my lore, the tale goes that her father (who lived in Wind, but does not belong to me, so I can't say this is his official lore) was the chief of a tribe in Wind, and sent a small group of his own to Arcane, to settle a sister tribe location there. Among them was his daughter, Luyten, who was a very talented warrior, and his son, Xxaven (the two were inseparable, especially since Xxaven's...incident) who was more of an herbalist / healer, and a trusted, skilled but intellectual warrior, Nitesh. Upon arriving to their chosen location, they met my progens, Demetrii and Milanka; however, when Milanka was exalted a short time later and Demetrii became a hermit, Nitesh took over as clan leader and has been such since.
Luyten has issues with always wanting to prove herself, and now that she's in her native territory at last, she feels stronger than she has in many, many years. Her time in other territories took its toll on her, as she's no longer elementally aligned properly. It took her a long time to adjust to the (in her own words) abrasive magic of Arcane, and her time in the Starwood Strand kept her awake most nights as the clan's activity shifted in madness, thanks to the influence of the strange flora there. The lack of sleep while in the Arcane territories was the first of many fractures in her elemental alignment. Nature proved much kinder, though the beasts here were much more ferocious, meaning more scars for her to carry. However, the everyday fight stoked the fires within her, bringing life back to her and reinvigorating her after the draining Arcane experience.
She stays with the clan (as a wanderer) out of loyalty, though she still aims to be the general of our "armies". She is a respected figure by all in the clan, and is a favorite among hatchlings (whose creations--the birdskull apparel--she wears with pride).
An example of someone who HASN'T taken to Wind well is Merlin; back in Nature, he had an expansive vineyard and created wine from it. However, with being forced to move from Nature and nowhere to grow a new one, he's turned into a ghost of himself (mainly as I try to decide whether or not to keep him, since he's so miserable :c )
These Wind dragons have no idea how to have a sophisticated time, and there's nowhere for him to get some nice wine, which is such a frustration for him.
He came into my clan with Enitan, and the pair were both welcomed easily as they're very warm, caring dragons, like most of the clan is.
