Rituals: A Mistbow Turned Rainbow

This magic is the result of many great minds coming together to figure out a way to save worlds from the titans that mindlessly consume them. the result of all this time and effort is a ritual that creates a mistbow, devoid of color, that greatly diminishes the reflectivity of light, and the warmth it generates. This effect temporarily drains away the colors of entire worlds, transforming itself into a true rainbow in the process. It then projects those colors deep into space onto a decoy object. The creatures on that world being saved, witness a massive mistbow appear in the sky when a world eater approaches their world. the world itself seems to dim & cool, casting the planet into a false winter, making it undetectable to by sight & heat. the light and energy that would attract the creature draws it to a decoy, that reaches further and further until things are safe. The rainbow then fades back into a mistbow, and the lost colors and warmth, slowly return.
