From the Introduction: I am sure many of you are wondering what happened to the enormous 500+ page work that was once the TCELMM. The answer is, we did not feel it was compatible with the Open Gaming License, and so to be on the safe side, we removed all creature conversions – which could have been in violation of the OGL. What you see before you, except for the illustrations, is 100% OGC. Take and use it as you wish. It’s smaller but more usable.
