Spock's drawn pentacle
In mysticism, a pentacle was a figure that consisted of a five-pointed star inside a pentagon that was used as a type of talisman designed to evoke magic. The Human religion of Wicca was symbolized by a pentacle. (DIS: "New Eden")
Spock drew a pentacle in 2269 as he attempted to toy with the art of magic. While standing inside the symbol, he successfully moved a Vulcan chess piece with his newfound "powers." A mystic symbol later appeared on the ground during the trial over the crimes of Humanity against the Megans. (TAS: "The Magicks of Megas-Tu")
