The Dark One's Curse is a curse featured on ABC's Once Upon a Time.

Cursed People



The darkness.

Centuries ago, after Nimue used her newfound magic from the Holy Grail for evil, the Darkness takes root inside of her and she becomes the first Dark One, being powerful enough to trap Merlin. Nimue lives in all dark ones after she dies.


The idea of the Dark One's curse is that only one person can be cursed at a time. Nimue the original Dark One, created the the Vault of the Dark One. After she created it she emerged the vault. The Dark One was then killed with the Dark One's dagger. The position and power of Dark One then shifts to the person who stabbed the Dark One with that dagger, and so on. Zoso eventually kills the Gorgon the Invincible and becomes the Dark One himself. Down the track, he tricks Rumplestiltskin into killing him with the dagger, and therefore Rumplestiltskin becomes the Dark One.

When someone is the Dark One, they possess incredibly unlimited power. They are immortal, unless fatally wounded with the dagger or they are fatally injured in an area without magic, in which the Dark One's name would simply vanish from the dagger and the Dark One's curse would end forever, which is what nearly happened in the case of Rumplestiltskin. If the Dark One stabs himself with the dagger, then it is the same case and there is no new Dark One. However, the Dark One can be resurrected with the Vault of the Dark One.

The Dark One's appearance and behaviour change explicitly. Their skin turns grey and scaly, their eyes become an animal shade of brown and their voice changes. As time goes by, the Dark One also exhibits and gains some murderous traits, becoming less merciful and more corrupted with the dark magic that is now flowing through their body. For example, Rumplestiltskin turned someone into a snail and crushed them, because that person accidentally and barely injured Rumplestiltskin's son Baelfire.

Ways to end the curse

  • If the Dark One falls in love with someone who eventually dies, they can give up their darkness to "The Guardian".
"When the Dark One finds Eternal Love at the Sun's brightest set where time stops, the path will appear to where the darkness shall rest."
  • Being fatally wounded by the Dark One's dagger.
  • True Love's Kiss, but only when Dark One treat it as a curse,
  • Being slain by someone wielding Excalibur.
  • In lands without magic, the Dark One becomes mortal again and is vulnerable to any normal threat.
  • Rip out his own heart and give it to other person, as a act of ultimate sacrifice and good.


Behind the Scenes

  • The Darkness is similar to the Venom symbiote from Marvel Comics. By itself, the Darkness resembles a strange black ooze that takes over a host, gives them powers and awakens their darker side.
