Is there any feasible way to get midjourney to use the same "character" each time ? The hedgehog and the girl (and the woods) just change - losing some emotional constant across the book.

I am "writing" a book about fairies with my seven year old and Inthink I might use midjourney for the background scenes and photoshop in her fairies, but ... yeah chatgpt and midjourney are kinda like twitter / FB - a mirror of our society and it's artifacts.
