Exalted: The Sun Rises From The Ash
Four massive spires can be found scattered around the Bay of Forgotten Ash. Wonders of a forgotten age, their function unknown, all fallen into disrepair or worse, they remain a mysterious landmark by which the sailors of the bay navigate. For they are large enough, distinct enough and spread out enough, that you can almost always see one of them one the horizon.
From the vast library and mechanisms stored in the Manse Reprieve in Wisdom on the Eye of Tranquility a glimpse of the function of the Spires is seen. Their original function was ward and seal, a lock on something ancient. Texts hint that the origin of this something was found somewhere in the Wyld, but no accurate record or tale has yet surfaced
