Population Migration / Travel
After The Fall of El-Adri, the High Elves set out on a journey across the Planescape beneath the banner of Gail-Idhren to find a new home.
Setting out on a massive migration after The Fall of El-Adri, the High Elves began a journey that would take them centuries, searching world after world, Plane after Plane, and location after location before finally settling down primarily on the world of Ea, on the Prime Material Plane. On this journey, Elves of all kinds broke off from the world-spanning caravan and settled down on dozens of worlds and many Planes, thus ensuring that Elves can be found almost anywhere as a result of this great Diaspora.
