A half-elf (ハーフエルフ haafuerufu?) is a humanoid being from the world of Aselia who plays large roles in Tales of Phantasia, Tales of Symphonia, and Tales of Symphonia: Dawn of the New World. Throughout the games, half-elves are often hated and oppressed by the others.
Half-elves are the product of a human and an elf mating, and half-elves carry traits from both humans and elves. Although half-elves' appearance typically resemble a human's, they possesses the elven ability to use magic. However, this has caused humans and elves alike to hate half-elves. Humans typically envy half-elves' power, and elves typically believe half-elves to have "tainted" human blood. Additionally, half-elves are able to live up to approximately 1,000 years due to their elven blood.
In Tales of Symphonia, Genis Sage explains in Torent Forest that he fears the future due to the fact he and Raine Sage will continue living long after their friends have died. This is further supported in Tales of Phantasia: Narikiri Dungeon when Arche Klein is still living two centuries after the events of Tales of Phantasia. In Tales of Phantasia, a measure of the half-elf discrimination from Tales of Symphonia still exists, for Arche, as a half-elf, is forbidden from entering the Elf Colony.
