The Thunder Plains are the site of a vast, never-ending thunderstorm. Many a traveler met their end here, until an Al Bhed by the name of "Bilghen" set up lightning rod towers to draw the lightning away from the main path. Ironically, he died after being hit by a stray bolt. With the arrival of the Eternal Calm and Sin's permanent defeat, the Al Bhed fortified the towers so the lightning would not harm travelers.
