I don’t know how and why, but the way your poetry frames these urban legends feels like it can speak to everybody at the table in wonderfully different ways. Like, a GM could use one of these as broad inspiration for a mystery, read another to the party and drop yet others into the game world as found flyers and each time the effect at the table would differ wildly. Truly makes me question how the format/medium influences what people get from something  👍
I hope some PCs try to find out who penned these dark prophecies in-universe…
