OMG I'M GLAD YOU ASKED

first of all, everyone is autistic!!! ok, Cahara isa bisexual transmasc demiboy, D'arce is a bisexual transfem, Enki is a demisexual non binary (he wouldn't give a shit about gender), Ragnvaldr is the cis person of the group, although bisexual, Le'garde is transmasc to me, but I've seen people headcanon him as transfem too, but I only see him as being attracted to men or being achillean.

Le'garde and D'arce have a queer platonic relationship, since Le'garde is not attracted to D'arce and D'arce has more of a religious delusion about godhood when it comes to Le'garde that others interpret as romantic attraction, they ARE best friends tho and knew each other for a long time. Even as kids. And overall Le'garde if it weren't for the apparent dissociative state after the dream, he would have brought the girl to live with him.

Also D'arce really enjoys sparring and often does it with Cahara, Ragnvaldr or Le'garde, they all sleep in a cuddle pile due to the dungeons being COLD, they are a polycule after all!

btw Nosramus is non binary and gay, could be added into the polycule, and they all try to help each other work on their issues (like D'arces dependance on Le'garde and lack of identity of her own plus deep rotted religious trauma, Enki's trauma with growing up in a cult and sister related, Cahara's possibly many bad stuff that happened as a mercenary and living in the streets of Jettaiah, and Ragnvaldr loss of his family, Le'gardes whole dream stuff)
