While I generally regard anybody who sues, especially anyone that rich, as a real jerk, I can see her point here. You put a lot of love and feeling and consideration for many aspects of personality into your character, and you really don't want someone else writing the 'encyclopedia' that is supposed to define them, give the last word on their lives, explain plots and storylines, etc. YOU want to be the only one who does that. If they were my characters, I'd feel that way even if money weren't involved. She created them, she wants the final say over what is considered 'canon.' Letting someone else use your characters to their own will is dangerous to your legacy, and can create real confusion among a devoted fan base (especially those who feel the characters are real) If you want an example of this, go to the bookstore and leaf through various Star Wars dictionaries and encyclopedias. On many subjects and character bios, you'll get a different story and a different answer every time. The contradictions are more stupid than funny. This is because Lucas never laid down the final law himself as Rowling is doing.
