So, trying to make a bowl shaped planet work with physics (even taking magic into account) is proved to be difficult – to put it simply. Even just the inside was difficult, but trying to make the outer side also have a proper gravitational field, proved even harder.
At many points I wanted to just say ‘it’s magic’ and be done with it. However that didn’t sit right with me, as I’m the type that needs things to make sense to me so that I can write consistently.
So that meant ironing out all the kinks, and making sure everything worked well together. You just know that someone will do the maths, so at the very least, it needed to be self-consistent. And this was just for the planet … most of it won’t even get put into the book!
However, situations like this is also part of the reason I started this blog. Aside from anything else, it helps to solidify the world in people’s minds (mine included). Besides, one of my ultimate goals is for other writers to be able to use this world as a setting for their own stories. As such, definite rules need to be in place – otherwise each writer will have their own interpretation of how it works, and nothing will mesh right.
Running various numbers as a person who failed maths A level, definitely wasn’t easy, and they’re probably not even correct, but it at least makes enough sense for me to start writing in the universe.
When I’m sure I won’t cause any spoilers, I’ll try to upload a sample picture of the crazy way my mind worked when trying to figure these things out. If, even after all that, no other author wants to write in this world, I’ll be sad. Naturally, though, as the creator I would still like veto rights.
I think Terry Pratchett also let other authors write in his disk world, that’s what gave me the idea for all this.
