Drippy the Peg Legged Rainbow

Rainbows have existed throughout the universe since shortly after its inception. Born from light and moisture, they have expanded along with galaxies and other cosmic goo. They only die from the destruction of worlds, absence of moisture or the long loss of light. Many are ancient, being nearly as old as the universe itself. Others are young, only born moments ago. All are beautiful, although many beings in the universe think them to be evil bearers of bad tidings and illness.

This is the story of one rainbow, neither ancient nor young . . .
