I have an odd and very specific problem... I was writing a fanfic for voltron and I realized that I want to write the plot of my fanfic into an original story since it's completely mine but with obviously voltron characters... do I continue the fanfic or cancel it so that I can write it out for my original?
As odd and specific as your problem may feel, I can promise you this is a burning indigestion that lives inside many writers, my dear.
The original idea for my Citrus Witches, actually came from a Merlin fanfic I wrote back when Geoffrey of Monmouth was still alive. It ended up veering far and wide from the original plot, only about 15% of it comes from that original fic I wrote, but the fact remains, it’s still there. I also took an entire scene from a Free! fic I wrote for this story.
If you feel a real connection with this story, and you want to see it take on it’s own life outside of an existing show, and become your own thing, I would definitely encourage you to do that. I think fic is a really great place to fine tune your writing and to spark new ideas, it’s up to you to decide what you want to do with that.
