Odin. Bork bork bork.
Isis. Great, now I have gender issues…
I picked islands/mead/steak, actually, and the “Find your enemy’s weakest point” as well.
I was trying for Loki on a tropical vacation, I guess. 
The first time I got Set and then I went back and answered the ones I was up in the air about and got Poseidon.
Set, even when I changed a couple of answers I was in two minds about.
I got the same as the OP. Hades first. (Then Odin and Set for the other two pantheons).
Congratulations!!! You are a proud member of the Norse Pantheon. Siding with the Norse puts you in the realm of the honor-bound, valiant warrior gods who are only strengthened by adversity. Never say die! Too much vision can lead to depression, but even though you and your fellow gods know your world is eventually doomed, your goal is to build your empires, fight your enemies and party with the greatest gusto you can muster up until the twilight of the gods. Your stunning Norse landscape of icy mountains and fjords, mysterious forests and rushing rivers will inspire you to great deeds of heroism.
A sneaky trickster, Loki is always feeling slighted by the other gods and determined to take revenge. Identifying with Loki can mean you have a good feel for the strengths and weaknesses of a situation or a system and intuitively know how to turn things to your own advantage. Your Loki power of persuasiveness and dis-information (deceit) contributes to success in psychological warfare, gaining unexpected allies, and unifying rabble and rogues to your cause. Beware of being tricked yourself.
Well, considering how I am half Norse ancestry, and already had a certain identity…
I am apparently Isis, Loki, or Zeus. Some might call that “inconsistent” or “confusing”, I prefer “multi-faceted”.
Tho am I. I can barely thtand up.
Set/Odin/Zeus . . . Go me 
I’ve given it a try from work.
So, I guess we’re all Set, & ready to go, then. 
Isis. Loki. Hades.
Oh…kay.
Isis, Thor, and Hades…
MPD?
Me?
Nahhh…
<nitpick>
It’s called “DID” nowadays, rather than “MPD”.
