Eden was a dark, hostile jungle planet.
It was the native planet of the Mandrels. Eden was also populated by a glowing insect with a bite that stunned. Eden also had carnivorous, people-eating plants which snagged its prey with vines and then drew the prey into its maw. Biting through a root would cause what appears to be green blood to squirt out and make it let go of its prey. A section of the plant was captured by Tryst in his Continuous Event Transmuter. Eden also had an orange atmosphere and was constantly bathed in orange twilight. (TV: Nightmare of Eden)
