On this night in the year, when the moon was right, the marshwraiths came out to dance and swirl. Poison found it beautiful to watch them, softly fizzing balls of ethereal light trailing phantom sparks as they looped and curled around each other. Nobody knew why they emerged on the same night each year, or why they danced and flashed their colours, gliding through breathtaking hues that went beyond the spectrum of human vision.
