Wicca was a Human religion, one of Earth's primary faiths as of the mid-21st century. It was often symbolized by a pentacle.
After the red angel transported a group of Humans in the East Fork Presbyterian Church from the bombings of World War III in 2053 to the distant planet Terralysium, the "New Eden" settlers "cobbled" together diverse faiths – including Wicca.

The Terralysium celebration of the harvest moon might be an element taken from Wicca.
