Hey there. I don't know if you remember, but I once posted on here about potentially using a magical system based on microbes like yours for a speculative evolution/world building project I was thinking of doing. After oddly enough a year, I'm finally going to hunker down and get started. I've come up with the system, but I'm a little worried it's too similar to what you came up with. Since someday I'd like to publish novels set in the world I'm creating, I obviously do not want to plagiarize anything. If you want, I can describe what I came up and it's backstory and a bit of how it works and maybe see if it's too close or not. I've only just begun work on the world, so if you think it's too similar or don't want to hear it, I can change course and even remove the microbial based magic entirely, but again since I'd like to publish things set in my world, I figured I'd avoid outright copying your work and world.
I certainly have no issue with your magic system taking some inspiration from my own. Kaimere as a concept is partially inspired by Narnia and its magic system has some influence from the magic systems of Star Wars and The Last Airbender. As you develop your world, its inhabitants, and their history, I'm confident it will become your own. Happy worldbuilding!
There are many Assembly bases on Earth and they have substantial financial holdings so safe to say they have top of the line equipment. Not all of it works in Kaimere (no satellites or cell towers for example and even their power grids are extremely limited) but they have a lot of tech they can bring in from Earth as long as it passes Free-States inspection.
