The Tartarians are thought to have been “Breatherians,” a being who does not rely on the digestion and burning of calories from food/water, but instead rather receives energy straight from the aether. The aether is thought to be the very fabric of the space time continuum that some would associate with electrons, the wind, the holy spirit, the atmosphere, and the gasses in the atmosphere such as oxygen, nitrogen, and hydrogen. Since the The Tartarians quite possibly had a completely altered digestion system than the one we now have, they had no need for toilets in their bathrooms. Which could hint at one of the reasons why bathrooms in the recent past have been used quite extensively more as social gathering powder rooms to not only freshen oneself up but to hear and spread local gossip.
