Xesto

The Xesto were creatures that consumed time and any form of temporal energy, including possible futures. Like Chronovores and Reapers, they were found in Gallifreyan legend. This meant that they could devour entire populations of any species in the universe, feeding on the amount of temporal energy they had. The Xesto were twice as large as a human, and either resembled a large weevil or worm. There were millions of them, and were usually found on Tick-Tock World. (AUDIO: Tick-Tock World)
