The themes in these stories are really dark and there is strong language FYI!!! For some of them you must be a member of deviantArt and signed in order to read them.
Pridelands: Forgotten Dynasty- Written by Rinjapine on deviantArt (the story is in the description of the drawings). Her explanation of this fic is: A fic about Mohatu's great-grandfather and his three daughters. Inspired by the dialogue in the TLK-comic "False Ancestor".
It gives an interesting beginning to the Pridelands as a whole and makes for a nice read. It is not a finished tale.
To my knowledge, the next part of the story as written by her is told in a comic. It is:
The Lion Queen: Trials of the Heart- The comic details Uru's life in Rinjapine's version. It is as yet unfinished, but it gets you up to the point where you can almost seamlessly transfer into the next fic.
Her description: "My take on Uru's story. It's long. It's tragic. It's bloody. What's not to love? XD"
The Lion King: The Demon Within- Rinjapine's version of Scar's life. Explains why he behaves the way he does, explains where Zira and her pride come from, etc.
Her description: "My version of how Taka became Scar, and all the events both before and after the first movie. I tried to tie together as many comics, books and other stuff as possible.
Every other TLK fic I've done is based off the events in this one."
Simba's Pride: Requiem- Her description: "My version of Simba's Pride, retold as I see it. Beware! I twist it in directions it was never meant to go."
She's got another fic that comes after that, but I've not read it yet. I don't agree with all of her theories, but the stories are brilliant nonetheless.
