Time Travel

Create a world where time travel is possible.

What are the rules of time travel? (example: time is fixed there is no changing fate, time is frivolous and any change can change many other things, or the past is fixed the future is a possible…)

How do the rules of time travel affect the story?

Why is time travel possible?

How is time travel possible?

Magic World?

Create a world based in magic, and after you have created this world apply the rule “there is no magic.”

How can you keep this world the same but not have magic?

What can you substitute magic with?

How can you keep the feel it had before by exchanging magic with something else?
