Pestilence

Then I saw when the Whale broke one of the seven seals,
and I heard one of the four living creatures saying as with a voice of thunder,
"Come." I looked, and behold, a white rider, and she who sat on it had a bow;
and a crown was given to she, and she went out conquering and to conquer.

The white rider make the sky color change. She even comes with several rainbow-like beam from the sky. Her appearence also changing when she passed through it.

The story based on Four Rider of Apocalypse, adapted by @addienfch
