So Was Ysayle A Warrior Of Light?

[TinyRedLeaf]

I think it is more naturally who affects the world the most instead of having the most crystals. They earn their title through actions that bring about Light to the world...

While it's true the WoL has more than earned his title, his power does in fact come from all six of Crystals of Light (now further augmented with the eye of Hraesvelgr), each of which he earned through sheer talent and heroism back in version 2.0.

It's been such a long time ago, that most players have probably forgotten that, in Her very first meeting with a handful of the Chosen, Hydaelyn did in fact explain what had to be done to defeat the looming "Darkness":

The power to banish the Darkness dwelleth in the Crystals of Light. Journey forth and lay claim to them. By thy deeds shall the Crystals reveal themselves to thee.

So, as Anonymoose said, in order to be the Warrior of Light, one must first be among the few blessed with the Echo. You must then be among the select few to be further shortlisted by Hydaelyn to hear Her plea to seek the Crystals of Light. And then you must actually take steps to earn the Crystals through your actions.

Even though Ysayle had the Echo, it wasn't entirely clear whether Hydaelyn spoke directly to her. She very probably did, given that Ysayle possessed at least one Crystal of Light.

But I further think it's implied that the Ascians misdirected Ysayle's zealousness, and tricked her into summoning Shiva unto herself, the very opposite of what Hydaelyn would have intended. From then on, Ysayle went down the wrong path, and was unlikely to awaken further Crystals of Light.

And that, unfortunately, is why she doesn't strictly qualify as a Warrior of Light.
