Every hundred years, the full moon aligns perfectly over Silverkeep Castle, unlocking the entrance to a secret ancient library hidden deep within its enchanted walls. This rare event grants access to the lost tomes and magical relics of the first grand sorcerers—texts and artifacts unseen for a century. On this one extraordinary night, two brave students, Eda and Sera, join their wise professor Corvin in a race against time to uncover every hidden object, spellbook, and magical item before the moon sets and the library vanishes once more. With the castle shifting and ancient traps awakening, they must rely on their knowledge, courage, and teamwork.
