Knowledge Tower



The Knowledge Tower was actually several different Towers, and they were located in Ko-Metru. When the Toa Hordika were searching for the Makoi Stones for Rahaga Norik, Nuju found his Stone in the Knowledge Towers. Knowledge Towers were grown by tossing a crystal into a basin located on the ground. The Ko-Metru Great Disk was found in an icicle on a Knowledge Tower. Prior to becoming a Toa Metru, Nuju also worked in a Knowledge Tower.
