Greya first talked about her experiences during this period.
Initially, after Greya had created magic on Illusion Demon Island, she temporarily stayed in Barbarian Cave. Even after Sanders went to the Abyss and Angel returned to the Old Earth Continent, Greya did not leave.
It was not until an Apprentice from Black Castle was sent to Illusion Demon Island to find Greya.
Although the Apprentice was sent by Black Castle, accurately speaking, it was Felicia who had people look for her.
Black Castle had experienced an undead uprising, and Isabella was the first to invite Felicia because Felicia had stayed at Black Castle with Greya, owing Isabella a favor. Therefore, Felicia honored the invitation and promised to think of a way to solve the undead menace in Black Castle.
However, Felicia, by herself, could not do much. Thus, she thought of Greya and called her from Illusion Demon Island to Black Castle.
