I myself am not non-binary, but I do have characters that are.
My protagonist Vernon is actually non-binary but would rather not label his gender in any one of the available, he was raised in a very positive enviroment that encouraged him to express any way he wanted to be, as a result he ends up with no real definition.
He goes by 'he/him' for the sake of simplicity.
But if you really want to i'll say as well ^^
Apologies in advance if the summary thingy doesn't work for a THIRD TIME IN A ROW
Here is a HUGE spoiler for season 1 and the development it will take
Summary
Summary
Drak'hog or drake for short, one of the villains of season 1, is actually pangender, but has a very supressed sexuality we will dab in latter when he becomes a party member in season 2 onwards
Here is a small spoiler of worldbuilding and lore that pertains to this (and has only been lightly touched on inside the story so far)
The dragons of JTA are mostly non-binary, they are shapeshifters capable of expressing any form they want so it is natural for them to have multiple genders, be fluid or even have a specific gender for each shapeshifted form
