How many Warrior of Light exist in story?

[Eloah]

Thats quite in depth and sadly I'm on my phone right now so i cant go into detail, but im curious about the Crystal of Light. Granted throughout ARR we get 6, so make sense others don't, but based on the Warriors of Darkness story we "see" or original Crystal was Water, and the rest seem to be the Blessing. My guess is similar to what Moose described. Hydaelyn gives her "Chosen" a crystal, but it wont manifest until they accept it. And should anyone show signs of prominence she will give them more. I hope we see more uses of our crystal so we can say, "we have a water crystal" or something.

Also to semi put the topic to rest just remember that the term Warrior of Light has different meanings not only in the game but to us as the player, based on the series as a whole. Since those two meanings arent lining up thats were the confusion and interpritations are coming from.
