Ruby, Anael, and Castiel all agree the Occoltum is "a place." An alternate reality compressed into an orb by Chuck.
When [[God]] created the world, He created the Garden of Eden, the crossroads between divinity and humanity, where he kept His prize creations, [[Adam and Eve]]. However, [[Gadreel]], the [[angel]] who was tasked to guard Eden and prevent any evil from entering, allowed [[Lucifer]] to enter the Garden. The [[archangel]]'s actions led to the corruption of humanity and their exile from the Garden. The Garden of Eden
was hidden away, and appears to exist in an alternate realm outside reality. According to [[Castiel]], no one has been there since the exile of humanity, however the Garden can be accessed if a non-human entity consumes [[the Occultum ]].
Within the Garden is a [[The Girl|young girl]] and an albino python snake. The young girl appears to have great knowledge of the Garden, but her actual purpose is not known. The snake or the nature of the Garden itself appears to have the ability to restore lost [[souls]] in [[soulless]] people.
