Population Migration / Travel
Their power broken, their magic stalled, the Elves leave the continent... or the world.
The Elves were beyond ashamed of their actions. wise creatures of many lifetimes, they had learned of the corruptions of power. But their pride never failed. When they chose to burn the Greenwood, hundreds of thousands of Elves used the magic inherent in the place to "ascend" (or so they call it, I call it dying) They became creatures of spirit, whispers in the wind. They are trapped forever more, with power, fleeting, and life: Immortal. Those who choose to remain in the worlds migrated, and made a new home in the northern jungle. There they reside to this day, eking out a meagre existence with the pomp and pride of kings, and the poorness of paupers.
