Eleti are sentient, civilized undead. Though tied to the negative material plane, and thus technically harmful to the universe, eleti like to point out that they have no impact on the ecology of whatever place they live in - consuming no food an creating no waste. They claim this more than makes up fot their negative aura.
Rules
Eleti can learn the following Supernatural Creature Powers:
Absorption, Abysmal Spines, Amphibian, Armor, Armor Killer, Awareness, Bane, Blur Form, Damage Immunity: Life (free), Death Grip, Death Resistance, Dematerialisation, Immortality, Inevitable Comeback, Instant Healing, Insubstantial, Marked for Death, Ward Breaker .
All Eleti also have the Supernatural Creature flaw, and can be turned and rebuked with magic. This is traded for their free Damage Immunity: Life schtick.
