Immortal Ranks

Mortal
The lowest rank. You can age, die, etc

God-status
You have all of the abilities of a god/goddess, besides a few select powers and being Immortal.

Immortal/Eternal
Being Immortal means you cannot die or age. The closest thing to death that can happen to you is getting destroyed (your particles are scattered)

Being eternal (not Eternal Energy) means you can die but you do not age. You can not die of natural causes.

Primordial Acolyte
The personal apprentices of Time and Space. You are not Immortal nor eternal, but your life force is tied with the Primordials'. That being said, it is very hard for you to even get hurt.

Super Immortality
All of the Major Gods are super Immortal. You can not die and do not age. You can not die of natural causes.

If you do get "destroyed", your body automatically puts itself back together.
