Specifically, were we always born destined to become the WoL, or, was that something that later happened, like we were some rando adventurer and Hydalyn saw fit to make us into the WoL?

Is the WoL like the Avatar Spirit in the Avatar: the last airbender series, where it's an immortal soul that transfers to mortal bodies for a time, or is each WoL unique?

Is the WoL ONLY good versus Primals, and therefore, pretty weak, or is the WoL a force of their own? For example, the WoL happens to get beat up sometimes by human opponents, but let's be real here... Omega and Shinryu are insanely powerful god beings... shouldn't the WoL be curb stomping everyone, if they can take down beings of that magnitude? I mean, isn't the WoL a god, essentially? I mean, primal beings of fire, water, earth, light, and so forth... those opponents all supercede ANY kind of human or beast, right?

What gives the WoL their strength and power? Hydalyn gave you crystals of light, is that it? So is the WoL just a regular human, but, has juiced up crystal powers because of the Crystal of Light that you had? Or, does the WoL have innate special power that is simply augmented by the Crystal of light?
