Regulus, if you want to be an "original idea TLK fan-fic author", you go to before the first movies. I know it's a bad term, but the "hipster" fan-fic authors all default to Mohatu and pre-Mohatu times. After all, one of the most famous TLK fan-fic, the
Chronicles of the Pride Lands, started in the Mohatu era. So no, your idea is not as original as you think.
Which reminds me: the biggest failings of
Chronicles of the Pride Lands, in my opinion, is the basically forced inclusion of Christianity into the TLK universe. If you watch the movie, the characters have a form of spirituality and the whole "kings of the past are stars and are watching you" deal. But at the end of the day, non of the characters mention, or even reference, any sort of God-figures, (Aiheu). So in one scene in
Chronicles, Simba is basically being poisoned by the bug diet. What do Timon and Pumbaa start doing?
SUPER PRAY!!!!!Spoiler alert, but it's not due to Timon and Pumbaa that Simba survives. /spoiler. A real annoyance button for me, IMHO.
Let's just say that while I enjoy the
Chronicles of the Pride Lands because of how well written and developed it is, there are many times when I just couldn't continue reading without a long break because of the God/Jesus/Aiheu deal that the author for some reason chose to shovel in. I mean... really??
