In the middle of creating the post... 
I am thinking of just limiting the deities to the original 12 Olympians. 
I don't think we will have enough people to fill the bracket as it is...
I am sorry for any inconvenience :/

***EDIT***
I will include Hephaestus making the total 13. For some reason, he is not counted in history as one of the primary Olympians but I disagree.
