Underworld

"All that matters is that all these people, in this Underworld, are dead and trapped because they have unfinished business."

- Mr. Gold to Emma Swan

The Underworld, mistakenly referred to as Hell, and also known as Purgatory or Limbo, is a world featured on ABC's Once Upon a Time. It first appears in the twelfth episode of the fifth season.

The Underworld is based on the location of the same name from Greek Mythology, and the Disney film, Hercules.

On-Screen Notes

 * It is possible to summon the spirit from someone in the Underworld either by getting the person's murderer to use the murder weapon to open a portal, or by using the Ale of Seonaidh brewed by the Witch from DunBroch.
 * Any souls trapped in the Underworld can be returned to any mortal world by Charon. However, they are branded with the Mark of Charon which will force them to return when the moon reaches its peak. The Mark of Charon can also be traded with another person, allowing the trapped soul to remain in the living world while the recipient of the mark takes their place.
 * Edward Kitsis describes the Underworld as "a weigh station between two other worlds". These worlds are Mount Olympus, which is above the Underworld and where dead people finishing their business are sent, and the "worst place".

Production Notes

 * According to Adam Horowitz, the Underworld is not Hell, but a place between Hell and the living world. It is described as "the place for people with unfinished business", which is not about being good or evil.
 * However, the Underworld is called "Hell" on several occasions in the series.
