The Great Being's Lab is a laboratory created by the Great Beings during their time on Bara Magna. It is situated at the end of the Valley of the Maze.The lab itself is a large stone chamber filled with mysterious artifacts of seemingly unknown origin. Whatever is there is mostly unknown, as the only trip to it ended without much investigation.
A bit more than six months later, Tarduk led Mata Nui and some of his Skrall through the Valley to find the Lab. Upon arrival, searching for anything of use, the Elemental Lords engaged them, already at the Lab and raiding it. After a fierce battle, the Lords departed with Mata Nui in pursuit of the stolen items.
