Each person on Megas-Tu is a specialist in a specific kind of magic, and while the satyr-like Lucien says there are no rivals, "generalists" such as himself are branded as troublemakers. The Megans harbor a deep-seated grudge against humanity, from a time during which many of them went to Earth. There, they were used, mistreated, and persecuted for their magical powers. The surviving Megans settled in Salem, Massachusetts, but fled there in 1691 due to many deaths at the Salem Witch Trials. Uniting their powers, they returned to Megas-Tu. Following their encounter with the Enterprise in 2269 (stardate: 1254.4), the Megans have said they will now welcome human interaction and no longer fear the advanced human race.
