[SPOILER] Who or What is Unukalhai?

[Eisen-Zorn]

I really don't know why people are trying to rationalize the power of the Warrior of Light in to simple, normal terms.

"They can't be a primal."
"They're not special."
"They only have power because of The Echo."
"It's all because of Hydaelyn."

While I'll say the first one is far-fetched (but not impossible), we'll just set that one aside for later.

1) They have, at every opportunity, proven that they are not just a normal adventurer or even like other Echo users. The Archons and Ysayle all have The Echo, but they pale in comparison to the power of the Warrior of Light.

2) The Echo, which does grant great power, cannot be the only reason why the Warrior of Light had managed to, essentially single-handedly, brought low every primal they've faced. All of the other Archons have The Echo, but, as far as combating primals goes, they lack the might to fight them. The Echo appears to only protect them from tempering.

3) Midgardsormr removed the Blessing of Light and blocked the Warrior of Light from Hydaelyn. However, did this remotely diminish the Warrior of Light's seemingly extraordinary fount of power? Nope. Still defeated Ravana, Bismark, and Two Ascians without it.

Then, surprising an immortal dragon who has existed for eons, the Warrior of Light managed to break through Midgardsormr's barrier and reconnect with the Blessing of Light. I'm pretty sure a mortal impressing the father of all dragons is something that doesn't happen all too often.

So, alright, perhaps the Warrior of Light isn't a primal, but the they succeeded in surpassing extraordinary long ago. Thordan VII saw it as he was dying, and, whatever it was, not even The Ascians have managed to pin down how to deal with it. These Extreme Primals? They appear to be tests to see if the Warrior of Light has a limit. So far, they haven't found it.
