The WOL and Mass Murder

[WhiteArchmage]

The WHM quests had nothing to do with damage vs. healing. The little girl wanted to heal using her own aether instead of drawing from nature. As that is lethal, you spend the entirety of the early quest line showing her that you can borrow form nature without damaging it :I

I'm calling shenanigans, I don't remember the exact quote but Sylvie doesn't even realize she's using her own aether until much later in the questline and it IS that she refuses to learn the attack branch of conjury. She outright says she doesn't want to hurt and only wants to heal, and it isn't until she uses Raise on a Wood Wailer and faints that E-Sumi-Yan tell her her mother was the same and died from consuming her own aether.

She wants to heal but she doesn't want to draw that aether from nature because she thinks that "using" nature's aether = you are hurting it. That is why she refused to learn about working with nature period and also why she wanted to only use her inherent "power" (ie. her aether).

I put this more on E-Sumi-Yan being a terrible teacher more than Sylvie's motivations. E-Sumi-Yan keeps telling us why Sylvie is in danger from using her own aether, while never actually mentioning the reasons to Sylvie herself until the revelatory quest.

It's possible E-Sumi-Yan told Sylvie offscreen, but she acts like the onscreen explanation is the very first she's heard of this, so I have doubts.
