[So death isn't eternal here, interesting. He wonders how that would affect him, he can revive by himself in a short time, thought the amount of time depends on the wounds and general condition of his body upon dying. Will he too lose something by reviving by himself? Will he be capable of reviving by himself at all?]

It may not apply. I suppose we won't know until I die, which I have no intention to do anyway.

[He frowns at Iris, this is starting to be more than a curiosity, not that he cares much thought.]

Athena is a Goddess, known to the world as a Greek divine being thought by now many believe that her and the rest of the Gods are just old myths and legends. She's real, the Goddess of valor, wisdom and war, but one that has reasons and helps the world progress, not the senseless war. That would be Ares' territory.

Athena became the protector of the Earth when Zeus, the leader of the Gods, left for a journal, where and why I don't know, neither I care, but it happened in the ancient times. Since then Athena has been fighting the other Gods who have tried to take control of Earth or have tried to destroy humanity. The Saints are her army for those holy wars, thought she despises seeing us die for her so she prefers to sacrifice herself if it can bring the war to a peaceful end.

What else fits with how things are in your dimension?
