Siklon investigated the disappearance of the Guardians and found traces of Arachna. Since Arachnas only appear at night, he asked you to investigate the Forest of Silence after the sun sets. When you investigated the forest after sunset, you discovered Shadow Goliants. After you defeated them, you returned to Siklon, who told you that they will keep coming back as long as their queen is alive. When Shadow Sheluk appeared after sunset, you defeated her. Siklon was very surprised and said that he would intensify his research.
