-My theories Well, mine randomly flamed when I had 1 of each kind of first generation nixphe in a flight. That was the same as Silvanon's picture hint, so I'm sure you have to have one of each beginner type.
Another thing is that maybe the symbols spell out something, maybe in Silvanon's made up language or one from ancient times XD Heheh...and basically, you have to spell something with them.
But maybe it's just random symbols. I don't know, but those are my ideas. :3
