The Loom of Fate was a magical device used by the Fates to weave the fate of mortals.
It needs a minimum of three immortals to weave with it. It is implied that the more immortals that work with the Loom, the easier it is to use it.
The Loom was used by the Fates to dictate the destinies of mortals for eons before one of their number Clotho, defected and took it with her. Finding the power the Loom granted too great to be possessed, and wishing for mortals to determine their own destiny, she broke it into three pieces and scattered them across the multiverse, disguising them as rings. They remained scattered until the rebirth of the universe after the Crisis inadvertently coalesced all the pieces onto one Earth, drawing the attention of the other two Fates to retrieve their power.
Quest for the rings
Clotho left one of the pieces in 1594 with William Shakespeare, who ultimately gave it to Philip Henslowe to give him more time to write his play Romeo and Juliet. They eventually took it back to the Waverider, planning to use it to find the other two pieces. During a mission to rectify an anachronism with William Shakespeare, caused by John Constantine and some of Legends, Sara and the girls found the first piece of Loom of Fate, disguised as a ring.
Later, Sara, Charlie and Constantine seek a second piece of the Loom of Fate. But Atropos arrives, destroys the Jump Ship, berates her sister for her betrayal, and seemingly kills Constantine. Charlie and Sara find the piece as a ring too. But Atropos, disguised as Constantine, intervenes, seemingly kills Sara, and takes the piece. Then, Atropos goes to the Waverider and finds the other piece. Behrad tries to stop her, but Atropos kills him by cutting the thread of his life, sensing that he was dead in the original timeline. She is about to leave but is intercepted by Sara, while the Waverider takes off and returns to the temporal zone. Atropos is shocked that she survived at their last encounter and they fight. Sara discovers that Atropos is unaffected by the Hellfire sword because she is a God. Atropos is about to finish Sara when she orders Gideon to open the cargo doors, but Atropos catches Sara's leg. Charlie arrives, cuts Atropos's hand with pieces of the Loom of Fate, and sends her into the temporal zone, saving Sara. The Legends retrieve the two pieces of the Loom but are saddened by Behrad's death.
Soon after, Lachesis finds the third and last piece of the Loom of Fate in 1918, where it was hidden by the Enchantress, and sends six Encores: Henry VIII, Brutus, Black Caesar, Jack the Ripper, Clyde Barrow and Bonnie to retrieve it, as exchanging of their freedom. Zari and John Constantine are sent back in time to retrieve it too. They pretend to be Encores, John as Jack the Ripper after knocking out the real and Zari as Cleopatra; they begin to seek the ring. Henry VIII is killed by Clyde before the search begins. Brutus is killed by Bonnie and Black Caesar by Clyde; the lovers do not like the rivals. However, they team up with Jack after discovering him. They capture John, but Zari arrives to save him. She uses her power to push Clyde on Jack's scalpel which accidentally kills him. John kills Jack with Black Caesar's Hellfire gun and Bonnie is killed by Zari when she sends back her bullet with her power. Soon after, John finds the last piece of Loom of Fate and they return to the Waverider.
Assembling and using the Loom
Charlie tries to use the Loom of Fate to bring back Behrad Tarazi but she is unable without her sisters and then a dog that Gary brings back from Hell mind controls Charlie into dumping the rings into their ship's garbage disposal. Later, the Loom is retrieved by Gary and handed to Ava. After doing research, the Legends decided that they must be immortal, at least temporarily, in order to use the Loom; to that end, they obtain the Chalice of Dionysus and drink its potion, making their bodies for one day strong enough to handle manipulating the Loom.
Shortly afterwards, the Fates used the Loom to change all of reality to create Loomworld, to suppress free will, and to have history rewritten. Clotho however struck a deal with her sisters so that Behrad Tarazi and the other Legends were alive, but as fictional characters in various television shows produced by Clotho Productions and aired on Fate+. When the Legends rebelled, Clotho took a portion of the thread of Zari Tarazi and split it; this gave Zari Tomaz a physical body of her own.
In "Loomworld", the Loom was kept in a room at a museum. John Constantine and Astra Logue attempted to use and focus Astra's magic to destroy it, but she became too distracted with memories of Lachesis. Atropos knew that the Legends were attempting to destroy the Loom and began a fight with Sara Lance; during the fight, Atropos was pushed into the Loom by Behrad and Zari Tarazi, using the Air Totem in tandem. Sara then pulled Atropos' life thread and entangled it with the other threads that the Loom was manipulating. The mixture caused the Loom to explode. Without the Loom, Lachesis and Clotho became mortals.
- Reality warping: The Loom's primary function is to rewrite/warp portions of a person's reality.
- Resurrection: The Loom can bring back the dead, as Charlie used it to resurrect Sara Lance, Behrad Tarazi, Gary Green and Astra Logue respectively.
- Time manipulation: The Loom can be used to manipulate timelines, even ones that have been erased, as Charlie used it to restore Zari Tomaz alongside her counterpart from the new timeline.
- Immortality: The Loom is what granted the Fates their immortality. Thus, once it was destroyed, the surviving Fates were rendered mortal (albeit they are still deities) and lost all the additional powers they were granted by the Loom (in Lachesis' case, those seem to be all of her powers, but in Clotho's case, those are only some of them).
