[center][b]Rules of the Earth Gods (Pre-Fall):[/b][/center]
1) Each of the Gods/Goddesses of the Seasons will represent a season as well as an emotion, like Jack with Winter and Fun.
2) They cannot be seen doing their magic by mortals.
3) When the Seasons change, the God of the season leaving and the God of the season coming formally exchange over the part of the Earth that they are in. 
4) When their season is no longer available, either the God is in the Heavens or they are in a place where their season is constant, like Jack with Canada, Russia, Antarctica, Greenland and such.
