Door to Gaias (InstanceTopic, 17)
From Compile Worlds
The Door to Gaias is quite literally a giant door in the Madou World. It is a portal to Gaias, created by Satan and Eldora, located in a secret pathway behind Satan's Castle. Supposedly, no mortal eyes, not even Lucifer's, we to befall the door, but Satan lead Arle Nadja to it anyway after being blackmailed with more bad making out with Rulue. Why no one abused the portal during Satan's rather excessive absence from the world is unknown.
