A group of Megans
Megans in the form of spirits
The trial
The Megans are an ageless species from the planet Megas-Tu that specializes in the ethics of magic and wizardry. The Megans are alone in their universe, there are no other lifeforms.
During the 13th century, the Megans traveled to Earth where they assisted Humans with the art of magic, and were eventually responsible for the ancient legends of witches and warlocks.
By the 17th century, the Megans settled in Salem, Massachusetts, after realizing that Humans only wished to use them to serve greed and lust. They chose to live their lives there as "normal men" to avoid the accusations of being "devils, warlocks and evil sorcerers." Unfortunately, while living in Salem, several of the Megans made mistakes and used their powers, and were burned for doing so, as witches during the Salem witch trials.
Those Megans who escaped the witch trials were forced to leave Earth and return to their homeworld, where they remained bitter and fearful of Humans.
In 2269, the USS Enterprise made contact with the Megans, but due to their distrust of Humans, they put the Enterprise crew in a recreation of a Salem witch trial. (TAS: "The Magicks of Megas-Tu")
- This episode has similarities with TNG: "Encounter at Farpoint", where Q put Captain Picard on trial for being part of a violent and child-like race.
