Legendarium/Series

Pre-Series
The Legendarium is a book that has the power to bring legendary creatures to life and can make legends come true. An evil wizard named Acheron created it, so he would be the greatest sorcerer of the magical universe, but he could not control it, which trapped him in the book. It was once kept in the Lost Library of Alexandria in Egypt. A Fairy Godmother named Eldora, who guarded the library, was the only one who knew how to lock it. She wrote all its secret in her diary.

Subsequently, she brought her apprentice named Selina to the library and accidentally read the legend of the Hawk Spirit, which invoked it. Panicked, she turned it into a pig and Selina returned it back to its book. While Eldora traveled around the world to find a way to lock it, she kept it in her house in the Forest of Flowers securing it with a barrier. Acheron dealt with Selina and told her that he would turn her into a powerful witch, and in return, she must work for him and free him. To prove his power to her, he turned her into the "Witch of Snakes". One night, under a full moon, Selina choose Acheron over Eldora and fled from the forest with the Legendarium.
