"unethical"

Quite dramatic to call it unethical. . .

It is up to you what you dio, but remember it should be fun for everybody.
I do think it is alright to look in the books, but it depends on the situation and I don't have a general rule about it. Well, I do have one rule and that is that I never use the encyclopedia of Arda to anything else than to come up with a question.
