Half Elf

Half-elves (also called Cha'Tel'Quessir in elven) are humanoids born through the union of an elf and a human. Whether a half-elf is raised by their human parent or their elven parent, they often feel isolated and alone. Because they take around twenty years to reach adulthood, they mature quickly when raised by elves (who think they look like humans), making them feel like an outsider in either place. Most half-elves are descended from moon elves. Pairings of elves and other races also exist, though they are rare.
