knowledge crystal

Knowledge crystals were objects used in Knowledge Towers to store information. Data could be recorded in the crystal by means of physical contact with a scholar, but the operation needed to be triggered by the will of that scholar.[1]


A knowledge crystal was a little larger than Toa Nuju's hand. If tossed onto the ground of Ko-Metru, a new Knowledge Tower would start to grow rapidly from where it landed. The new tower would grow to full height in mere seconds.[2]

Knowledge crystals about the size of Matoran's hand were used to grow new Knowledge Towers. They were thrown into special cradles located at different places in Ko-Metru, from which they grew at a rapid pace until a new tower stood alongside the old ones.[3]
