Empresses in the Palace Fanfiction 甄嬛传同人文

I'd like to read books similar to Ascending to the Heavens. I'm looking for fanfiction based on Empresses in the Palace. I hope the author will write all the girls as fully rounded characters, each with her own reasons and consequences, without prejudice or a biased perspective. Most of the stories I've read so far either get the rules of the harem wrong or have the characters completely out of character.
