It used the D20 system, but had entire new classes, magic and races.
My question mainly is: How much can you "take" from a OGL source, could someone, for example could someone take the non-rule concepts of the Mojh race (humans-transformed-into-reptilians-folk) into a new game setting with different rules? Or even take the Witch class (Magic users similar to sorcerers) and use them in a non-rpg story?
