Mouri
The Mouri were a group of entities who lived in stasis in The Temple of Atropos on the planet Time. They were the only beings capable of controlling Time and were "assigned" at the beginning of everything as a means to keep control of time. When the temple was operational, all of time would pass through the Mouri who were especially equipped to withstand the power of time.
