I looking at the 1983 DM Players Manual and noticed in there that there was a Centaur. Then I thought of the Centaurs natural enemy the Minotaur. What if there was an adventure pack that was called.. "Minotaur Maze"
It would be a bunch of small islands(the big one being the Minotaurs home and a medium one that is the Centaurs home). The Minotaur King has taken the new Centaur prince prisoner and wants the Centaurs to do slave labor for him. It would be several quests leading up to the last fight with an evil Centaur controlling the Minotaur King. In the end you would save both races from the evil Centaur.
I just would like to see centaurs in the game and maybe, just maybe add centaur as a playable race at the same time.
Just dreaming here, but that is my suggestion.
