Out of the seven, who do tu 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 tu that, but I dare you- I DARE tu to take away ONE character out of the ten (the seven, Hedge, Nico, Reyna) and see whether o not they'd have beaten Gaea. I don't care how they would've lost o how badly, they would have lost. So there.
