My dearest Valin,

I fear you are misunderstanding what it is you may have done, or think
you did, to your son, Micah. Darkness is not a disease of the physical
form; its a disease of the mind that festers only as long as the victim
allows it to. There are indeed cures for it, and healing that must take
place, but the healing must take place from within, not from without. So
to anyone else reading this missive, I will ask you as well to try not
to attempt to heal Micah, for your hopes would not come to fruition.
Darkness is a disease that thrives on ignorance, not a physical
abnormality.

In Faith,
Searoth Fiadhaich
