This seems really cool, and I'd love to make up a character.
Just one question; what do you mean by main character & side character? Sorry if that's a silly question :0c

Awesome! There are no bad questions. Your main character will be the person that you build all the way from the moment they find themself in this world. Through that character, you will go on diverse adventures and obtain new powers. 

Side characters are more like static support characters. They are there to help drive the plot and give the main characters more people to interact with. But you will not be character building these guys and gals. 

That make sense?
