This gives absolutely no background info so I'll just put something random :/ sorry maybe comment something so I can help you further.
Honestly cannot help you with even what you've given me.
But I know alot about dragons, from watching the astounding shows Game of Thrones and House of the Dragon
Here's a little summary that's random
I’m not going to talk about whether dragons are biologically plausible (short answer: they’re not). I’m going to talk about something which is in certain ways even less plausible: the idea that certain human families have heritable dragon-ness, which gives them an affinity to the beasts and a certain resistance to fire. This is explicitly stated of Daenerys: she can hang out in a funeral pyre overnight and be relatively unscathed. And she can, with a certain amount of effort and willpower, control Drogon. Viserys claims to have the trait but doesn’t, to horrifying repercussions. And certain other characters in later books either seem to have an affinity to dragons – although they haven’t been tested with fire as of yet – or think they will with, again, unfortunate repercussions.
