I often hear the colloquialism "Seven Hells" or "Seventh Hell" from NPCs, and I always wondered about it. It seems to be a prevalent phrase across Eorzea, possibly connected to the Twelve mythos. At the same time, many Eorzeans acknowledge that the dead (unless anchored to the corporeal realm) diffuse into the Aether.
So what in the Seven Hells are the Seven Hells? Do people experience actual realms while drifting the Aether? Are they arranged according to type of sin like in Dante's Inferno, or severity? Both? Are there any other concepts involved?
Finally (and I won't hold my breath on this one) will we ever go there? (inb4 snarky answers like "you might")
