I'm planning to write a comic book about Brazilian Jiu Jitsu. All the characters are fake, but they talk about Brazilian Jiu Jitsu history. They explain the origin of Brazilian Jiu Jitsu and mention the masters Helio and Carlson.
I didn't find a forum about writing books, and this is the closest I found.
Do I need to pay royalties or ask for some kind of permission to the family?
