Immortal

Immortals, also called Immortal Beings, are a species of supernatural beings that are truly immortal and cannot be killed by any weapon. The term "immortal" is used to describe the species into which Silas and Amara, the very first immortal beings in history, were transformed when they consumed the immortality elixir created by the witch Qetsiyah.
Immortals can be considered as the template for the Original vampires and, in turn, all vampires. However, immortals differ to vampires in many different ways, and vice versa. The biggest of those differences being that they are still alive, rather than being undead like vampires, who must die after ingesting vampire blood so their bodies can be magically reanimated. They also do not possess superhuman physical powers to the same level as vampires; however, they do possess far superior range of psychic abilities than vampires.
