Everything starts from the beginning of the Justice League Dark (JLD) story.
The best way to summarize why the JLD team is being rebuilt is because after events like Dark Nights: Metal and No Justice, as well as the recent events in Justice League have shaken up the universe, so
Magic in DCU can be understood as a type of ability used through `summoning` using many different methods: Divine objects or holy objects, spells, reading words backwards (like Zatanna often does) etc.
Wonder Woman also discovered these things, she also wanted to participate but was rejected because the magical world is people from the Underground, and Wonder Woman is considered `Showbiz people` and they don’t want her.
However, events force Wonder Woman, Bobo Detective Chimp, Swamp Thing, Man-Bat and Zatanna to investigate to the bottom of the creatures of pure magic known as The OtherKinds.
And they found out that the person in charge of stirring up this magic was… Dr.
This caused Nabu to open a portal that called upon an entity of The OtherKinds, the Upside Down Man.
At that moment, a mark on Wonder Woman’s forehead glowed, she `turned chaos` into a form of extremely high magical energy that was strange to everyone, and she repelled the Upside Down Man.
All is explained in the event that takes place immediately after, Witching Hour – JLD’s first main event and crossover through one-shot titles such as Wonder Woman and JLD Witching Hour and JLD and Wonder Woman Witching Hour, as well as other titles.
Through the explanation of Circe – Wonder Woman’s former sorceress, whose magic was given to her by Hecate – she explains that Hecate left a piece of herself in 5 different people to hide her magic.
Hecate plans to control her puppets to kill everyone related to magic and attack places that emit magic such as Nanda Parbat in Tibet and Mount Olympus, the way she wants to purify magic to
Wonder Woman became Hecate’s most powerful henchman, and no matter how much Wonder Woman tried to regain control, Hecate stopped her.
However, Wonder Woman’s control accidentally allowed her to `reach` into Hecate’s true thoughts.
Wonder Woman makes one last attempt to regain control, and takes advantage of Zatanna’s `damaged` magic to open a portal for the Upside Down Man to appear as a god and `destroy` Hecate, freeing Wonder Woman from the curse
However, there is still a fifth character who will have all of Hecate’s abilities, just like in Avengers vs X-Men when Cyclops defeated Emma to get the last piece of Phoenix.
