"Games Workshop Intellectual Property". 2005-11-12. Retrieved 2007-06-16.: "We encourage fellow hobbyists to invent rules that work for them. There is no need to stick precisely to the published rules. However, if you are thinking about making your own Codex [eg.] for your Space Marine chapter (in addition to following the other guidelines in this policy), please avoid making it look official as this may confuse gamers and amount to a challenge to our trademarks. Also, do not copy our official publications or documents."
