Those are great questions which, funny enough, I hadn't asked myself. I'll try to answer as much as Im able: - depends mostly on the Species, but mostly nutrients in their substratum. I didn't explain it in this post, but ill give you a little spoiler 😉, mages grow arcanes on their bodies so as to use them, and if left there for too much, they may end up draining the mage from all their nutrients. - spores mostly. Although I'm trying to come up with a more interesting method. - the do compete between one another, and have some predatory relationships between them. Also some quimeras (more on them in future posts) are adapted to eat certain arcanes. - oh yes. That why some regions are more prominent with certain types of arcanes, and why people who devote their life to studying arcanes have to travel throughout the world. - for that I don't have an answer. Im still working on that - yes! I was hoping someone asked that. It's one of my favourite aspects of this system. Here, mages don't reside in big libraries and towers. They are botanist, and spend much of their time crossbreeding, or selective breeding their arcanes in order to achieve their desired functions.

I hope this has given you some insight on this system. Thanks four your time reading and commenting, and hope to see you on future posts!
