"I fall asleep in the full and certain hope
That my slumber shall not be broken;
And that though I be all-forgetting,
Yet shall I not be forgotten,
But continue that life in the thoughts
and deeds of those I loved."

With memories so hazy, Kasha has forgotten his work and role as a Diver, and firmly believes he has died and now traverses a realm meant for the dead. No matter how many times others try to explain that he is in The Nightmare Realm, Kasha refuses the truth; in life he had feared death so now, thinking he wanders death's domain, Kasha has vowed to conquer death itself and find a way to manipulate it. Great things done in life are memorable, but being the first tame death transcends all.

But denial of the truth holds Kasha back, for how can he master death when he refuses something as simple as words spoken by another.
