Out of the seven, who do you think is the most important to the prophecy?

Most important? No. There is no "most important". All of them are not equally important, I'll give you that, but I dare you- I DARE YOU to take away ONE character out of the ten (the seven, Hedge, Nico, Reyna) and see whether or not they'd have beaten Gaea. I don't care how they would've Nawawala or how badly, they would have lost. So there.
