|“|| Hayley: What kind of curse? |
Eve: Swap nature around, inside out. Made it so their natural state was wolves. They only turn back human on the full moon.
— in The River in Reverse
During the summer of 1991 the vampire Marcel Gerard asked the witch Brynne Deveraux (unknowingly possessed by Celeste DuBois) to curse the Crescent Wolf Pack so that the werewolves remain in wolf form perpetually and reacquire the human form only during the full moon, thus reversing the curse of the werewolf that forces them to change into wolves during the full moon.
This curse has remained active until 2012, when Andrea Labonair, better known as Hayley Marshall, the current queen of the Crescent Wolf Pack, forced the witch Celeste (who currently possessed the witch Sabine Laurent) to break the curse.
Later, the curse was placed again by the powerful witch Dahlia on Hayley, Jackson and the rest of the pack in 2013 that, as alphas of the pack and linked to the rest of them through the Unification Ceremony, they widespread the curse to the whole pack. This was done because Klaus wanted to prove to Dahlia that he doesn't care about anyone anymore (except for Hope) and would do anything for his daughter. Also, it was seen that he was hurt/enraged when Hayley decided to take Hope away from him, so that is why he proved his point to Dahlia by harming Hayley - punishing her for trying to take his daughter away from him, and proving a point to Dahlia; killing two birds with one stone.
Months after Dahlia cursed Hayley, Jackson and the rest of their pack, Davina Claire made a tempting offer. After Kara Nguyen tried to fracture Davina's hand and enrapture her in a circle of fire for not following her orders, Davina struck a deal with Hayley on the one night she could be in human form and see her daughter: Davina would block the curse that was placed on Hayley, Jackson and the rest of their pack if Hayley killed Kara Nguyen for rebelling against her (to place fear in her coven for not listening to her). Hayley did just that and killed Kara, along with a few other unnamed witches. Davina blocked the curse. One month later The Ancestors agreed to grant to Davina the power to lift away the curse.
The curse is currently not active.
- This curse can be modified to affect unconventional types of werewolves as it was originally cast on ordinary werewolves of the Crescent Pack and later cast again on the non-original hybrid alpha of the pack (Hayley) and the rest of it whom were evolved werewolves.
- The only types of werewolves it has yet to be used on are the Original Hybrid (Klaus), the Tribrid (Hope), and a witch-werewolf hybrid.
- The curse was active as performed by Dahlia.
