"The true harm of killing itself.
But it did not know how to."
Athena read before she dove into the explanation for the same.
"Still, considering the Sir William and Lady Morgana's story. It feels like he is trying to say that the true harm that ever happened to the creature was not of his doing, but of its own. Feels like he is making reference to Lady Morgana taking her life. That her final attempt to freedom was the biggest horror that her soul had been subjected to. But that really does not make sense."
