A crystalline city lies deep within the Dimension of Light sparkling in pure brilliance. Rahkshi of Light patrol the streets keeping watch over the matoran that reside there. The city is built out of Knowledge Crystals and contains the Onu-Metru archives beneath it. This was the realm of Garadur before he fell. Matoran study here learning the secrets of the universe oblivious to the world outside of this small realm. Here all is happy and peaceful.
(Hau shielding protects the city from any freak weather phenomena.)
