Moon Elf

"Moon elves tend to have a nomadic attitude, often seen traveling in a monarchical society, craving a life on the road, often exploring unexplored parts and forests between cities and villages. Moon elves are different from their other elven cousins, as they have more of an extroverted attitude due to their nomadic lifestyle, getting along uncommonly well with other races."

Moon Elves of Aneirys appeared roughly at the same time as the Dawn of Finality  , though no reports of Moon Elves existing in vaults have been found. Rumors surrounding this races origins have been present since the beginning, with the common theme being that they somehow bridged the gap between this world and the Feywilds.
