The curse originated from the druidic order who followed Goldrinn, known as Druids of the Scythe. They shapeshifted into the feral worgen and eventually lost their minds to its violent nature. The other Druids agreed that they must be locked away, and thus put them into eternal slumber deep beneath a tree... until the days Arugal utilized Ur's research, and Velinde Starsong used the Scythe of Elune. It was the night elves, after all, who created the curse in the first place. Obliged to help their newfound allies, they re-introduce them to the Alliance.
