Tree of Savior - Acquiring the the Light of Salvation

After fixing all the purifiers, the Revelator goes to save the kidnapped miners from a giant spider. After the rescue, a miner tells him to gain access to the Closed Area (where the Light of Salvation is supposedly located), he must collect stones carried by monster to insert them on the wall. He eventually gains access to the Closed Area and touches a crystal, revealing the Light of Salvation a mysterious slate. Per Commander Uska's suggestion, the Revelator brings the slate to the Bokor Master. There, the slate reveals a message from Laima, the goddess of fate and wisdom, who tasks the Revelator to collect all of her revelations to restore her form.
