The Grey-Devourer of the Rainbow Festival

The Rainbow Festival erupts in an explosion of color: ribbons flutter, soap bubbles drift through the air in rainbow hues, and music sounds on every street corner. Stalls overflow with sweets and glittering trinkets, and children race whooping between the legs of the dancers. But beneath all that gaiety you feel something shifting, something cold and patient and hungry.

At the great fountain the color begins to bleed away. A gray stain spreads, and everything it touches loses its hue, its sound, its joy: flowers wither to ash-gray, laughter falls to silence, and revelers stare ahead with empty, colorless eyes. A shadow is feeding on joy itself, and the festival is its most bountiful meal in years.

You track down the source of the grayness, rouse the drained children from their stupor, gather the brightest colors and loudest sounds of the festival as a weapon, and solve the riddle of what lured the shadow here in the first place. Along the way you discover that the anxious festival organizer knows more than she will admit.

At the heart of the fountain waits the Graygorger, a shadow-spirit of forgotten joy that longs to snuff out every color until the world is as gray as itself. Wherever it passes, everything fades to colorless silence. Will you rekindle the festival in full color and drive off the Graygorger, or will the last light go out and the laughter fall silent forever?
