The Dominion of the Celestials and Makuta was a very large, loosely defined political region of space that existed between 100,000 BBY and 49,000 BBY . It covered much of the western half of the galaxy, and also some regions to the far north and north-east of the galaxy that were outside of the League of the Six Kingdoms . Much of this territory would later become the unknown regions. This region was under the direct control of the Order of Mata Nui, and patrolled by the Makuta . The celestials carried out many experiments here, and it is unknown to what extent the unknown regions was affected by their presence.
