Half Elf

Half-elf is a term used to describe the offspring of an elven or half-elven parent and a parent of any other species (such as a human). There are other races that are half-elven, but they usually referred to by other terms.

Most half-elves are the hybrid offspring of both a human and a high elf, a human and a half-elf, or of two half-elf parents (a half-elf of high elf and half-elf descent is unlikely due to high elven prejudice). They usually have a combination of physical characteristics from both sides, and can be recognized as half-elves on sight.

Shortly after Vamir destroyed everything, two portals opened up into different areas and Civilization started being built around them.
