A blue green jewel, Beta Delphini II, home of the turtle like Chelonians. The world is old, and bears many scars, the craters from orbital bombardment and high power explosions, rings of dust and debris that were once starships, habitats, and fighter craft. But the world below remains tranquil, its wounds covered with blue seas and green forests.
One day a a wind begins to blow out of the West. The next day it gets stronger. And stronger still the next few days. Eventually (and fortunately), the speed of the wind tops out at a steady fifty miles an hour, but continues to blow. Soon an entire kingdom is wondering why it's not abating. The weather mages deem it unnatural but can't seem to banish or control it. The priests of various faiths claim it's divine. The End-Of-Days crowd is having a field day with their predictions of doom. No one knows why the gale persists. When inquiring with neighboring kingdoms, it seems they too suffer from a persistent western mistral. Eventually the populace begins to adapt to living with a twenty four hour a day wind. Always from the West, and perpetual. What could be causing this? A raging Elemental king? a curse from the gods? an unearthed artifact? Or has Nature itself gone haywire?
