Pretty good questions, Choco..

I do believe I had brought up the thing about the Roman/Greek Gods being the same earlier cause Jupiter/Zeus is the same God.. {my knowledge in Roman/Greek myths might be rusty but I think I do remember the basics involving their Gods, same with Egyptian. It's the Norse Gods I don't have know much about, the only exception being Loki whom I believe is Norse.. he might not be..} just the Romans prefer to him under a different name.

And yes.. there should be a power cap or the person has one or two abilities.. esp. for people who are blessed by the more darker Gods {Loki/Anubis/Hades or Pluto} could be more tempted to abuse the powers they are given, depending on how corrupted the person's soul is or what their intentions for those powers are..

And I honestly thought in a way, they were all born with them.. or at least.. Noelle was born with the ability of being able to judge and steal/take souls.. if that is okay, Natsu.. I could change my thinking on that and cause Hades can be cruel, Noelle entered a contract with him to get those powers for her revenge in exchange that Hades could have her soul after she takes her revenge.. < . <;

And I guess how long they have the power depends on which God they are bless by and why they received those powers or what they use the power for? I'm just doing a guess, it's really up to Natsu since this is his roleplay..
