The Final Move

As there are four Protruding Books in the Case, touch and interact with the top right one out of the four. And once players have done this part, they may hear a click. That is the sound of your first correct move. Moreover, notice a pedestal-like object known as Ancient Alter on the same side opens up.

After it opens up, turn around and get over to the other side of the Library, where a glowy Heart is near the Sacrificial Alter. Collect the Heart and take it to the Ancient Alter. Players can gather the Heart in the Inventory for safety.

However, when you take the Heart to the Alter, it may not work. Press the space to drop it in the Altar. And then the secret chamber will open up on its own.

Remember to do all these things correctly; if you do not follow these steps, your character’s life may be in danger. The Library is a mystery, and it can create a deadly foggy area if there are intruders, so walk cautiously.

After getting into the Hidden Room, you may find a dead pixie or a tiny fairy beside a ritual circle. You can either destroy the ring and ruin the ritual, or you can gather all the Moon lantern pieces and ignite them to perform the ritual.
