Zone of Darkness

The Zone of Darkness was a pocket dimension in the Bionicle universe. It was pitch black, so dark that it was impossible to tell what the landscape looked like. The Zivon lived there. The only beings that could open a portal to it were Kahgarak, with their Rhotuka spinners, or any being with an Olmak.
