Immortal

The Immortal appear to be a sub species of Human which is very difficult, if not impossible, to kill. Immortals are very similar to Humans, yet cease aging at a point, and can heal from all injuries almost instantaneously.

Evidently, one cannot know if they are an Immortal until their death. (
