"The gatekeeper of immortality…" Arad started thinking, "What about vampires? We're immortal."
"Age immortal, you still can be killed. True immortality is when you don't age, can't be killed, and won't grow insane for the long life." Hati looked at Arad with a smile, "The Tarrasque was an immortal since long before Gracie came to power. She was a spark of life force, and so Gracie never robbed her immortality. The over-god is the world itself, so she is outranked by him. And I'm quite special, I'm not exactly immortal, but eternal. Those are close enough to be similar in effect but different in the fundamentals of their nature."
