Star Elf
  The green depths of the Yuirwood hide an ancient secret long forgotten by folk beyond Aglarond's borders, and not widely known even within - the star elves, an elven subrace that retreated from Faerûn to an extraplanar refuge known as Sildëyuir. Sometimes referred to in ancient texts as mithral elves, the star elves concealed the existence of their hidden kingdom for almost two thousand years, leaving behind nothing but mysterious ruins and old, strong magic in the stone circles of the Yuirwood.
  While the star elves have kept themselves apart from the rest of Faerûn for many centuries, their isolation is coming to an end. Besieged by an insidious peril from beyond the circles of the world, they face the possibility of being driven from Sildëyuir back to their ancient abode in the Yuirwood.
  Of all the elven subraces, star elves most closely resemble moon elves. They have pale skin that sometimes takes on a pearly gray or faintly violet tinge, and hair of gold, red, or silver-white. Their eyes are gray or violet; sometimes with gold flecks. Like the sun elves or moon elves, star elves are tall and slender. In their homes they favor elegant, embroidered tunics but dress in neutral colors with dappled gray-green cloaks to remain unseen in woodlands. Star elves are graceful and strikingly handsome by human standards.
Outlook
  Star elves are cautious and aloof, keeping an emotional distance from events. They can be judgmental, although they take their time and consider many factors before passing judgment on a creature or action. Once won, a star elf's friendship (and enmity) is deep and long lasting. Star elves love beauty in any form and have a knack for perceiving inner beauty rather than outward appearance and actions. Among their own kind, star elves delight in song, dance, and works of magic, but away from their homeland they are slow to bestow the gift of their voice or artistry.
Star Elf Society
  Most star elves have removed themselves from the everyday life of Faerûn and therefore have little understanding of humans, dwarves, and other races. They think of humans as aggressive expansionists who readily take up blade and spell to get what they want, and they regard humans with caution. They get along well with other elves, especially sun and wood elves, but fear trouble from the moon elves' unguarded generosity and engagement of human realms.
  Most star elves prefer not to involve themselves in the world's: troubles. Star elf society values individual accomplishment and rights over collective effort.
  After two millennia in isolation, star elves have realized that they know little about the world from which they took refuge. As their ancient haven no longer shields them entirely, many have begun to debate whether Sildëyuir should remain closed. Certain Faerûnian realms might make powerful and reliable allies in their war against the abominations who threaten Sildëyuir. A few have taken it upon themselves to spy out the lay of the land, seeking knowledge to defend their home - or a place to call their own if Sildëyuir must be abandoned.
Language and Literacy
  Star elves speak Common and Elven. Those who venture to Faerûn from Sildëyuir often learn Aglarondan, Mulan, or Rashemi. In their refuge, Auran, Celestial, and Sylvan are common, while some star elves learn Abyssal and other evil tongues to converse with those seeking to destroy Sildëyuir.
