Fantasy lovers, this is for you! Magic doesn't work the same way in every fantasy story and can be implemented differently. I want you to come up with a system of how magic works in a fantasy setting. Simply knowing the words of an incantation can be a baseline if you want, but I'll need more details. Here are some things to cover. 

1. Where/when did magic originate? Was there a certain time period or event it was traced to, or has it always existed? 

2. Must people be born with magic or can anyone do it?

3. Are symbols, objects, or certain actions needed to do magic? 

4. What is the source of magical power? It can be unknown or uncertain.

5. Types or classiciations of magic. 

Any other relevant information including if there are schools for magic, are there restrictions on who or where it can be used, how often can it be used, etc. 

The more creative and in-depth the better. Most importantly, have fun!
