That's right.

In order to fuel the lamp, I need the oil from the trees that grow in this forest. However, the trees only take root from something special: from someone who's given up and given in to despair.

Each time someone died, or murdered, they were overcome, and took root. Usually, I'd have to wait for others to wander into the forest and get lost. It. It's a really long and...unpleasant way of doing it.

But this way? I don't have to feel any sympathy for those who might give in.
