"When creating your character and playing the game, you will get the chance to flesh out the lore of the world in the process"

Does that mean I could make a culture/nation for my character backstory? If so, *turns Super Saiyan* I'm in.

As for magic, would it be okay if my character used it more for utility than combat? I still plan on having side effects depending on the circumstances, such as mental exhaustion, and at worse, mental instability. Also, could I make another character later in the role-play?
