Population Migration / Travel
Growing cultural differences between the elvish subspecies creates a migratory movement to found their own lands.
With selenite being treated as both a religious medium and a key to technological advancement, the Elves begin to develop tension regarding which of their newfound cultural beliefs are the "correct" ones. Unable to settle the differences between new traditions and a rapidly changing culture, they split into three groups based on ethnicity and begin looking for land to call their own.
