Celestial Elves

The following is quoted from The Elven Folk (book):

Not so much a clan as a designation, the City Elves (or Celestial, as they like to be called) is any Elf who no longer dwells in a clan. Celestial Elves are who helped build Leth Deriel and who initially ruled Shard. Celestial Elves commanded the Empire when the Empire still stood. Since they come from many varied clans, they do not have any particular appearance.

Celestial Elves are fairly recent, having existed officially since approximately fifty years before the arrival of the Seven Star Empire, a blink of an eye to an Elven Lorethew. Their leader is Nelix.
