I'm having problems getting a clear picture or idea on what types of powers my characters should have. Since they are to be the rulers of the north, south, east, and west, and are quadruplets born to a god and goddess, I was going to make them all have the same types of powers. The idea was that, their emotions will be connected with the change of seasons. Earth, wind, fire, and water they would be able to control them all. But my husband suggested that I separate them instead. Have each control one element, so in the end they would have to work together to defeat their father and bring balance back into the world. Doesn't that sound so much like the "Avatar, The last air bender"? I've watched all of them and I don't want my novel to be like that. Any suggestions would be much appreciated. Thank you!
