The small spirit of energy known as the Tantabus seemed to undulate with excitement before it dutifully served its mistress and floated above her. It settled in the shattered stained glass window that once depicted the shared unity between her and her sister. It instantly transformed into a dark, spherical crystal large enough to blot out the sun. In a single pulse, it ripped control of the dream from Luna. Day turned into night as the spirit fired multiple beams of darkness into an expectant and unmoving Princess Luna.
