Free of Sin

Sunny had an inkling that the Mad Prince had not been willing to quietly disappear for a while now. However, it had always been just that — a suspicion, substantiated by nothing except for his knowledge of himself. 

Sunny wouldn't have wanted to cease to exist, so why would his Defiled version be any different?

The Mad Prince had wished to be free, and in the process of fulfilling that wish, he caused Neph's death. His soul was consumed by the Defilement, but not entirely so — a small sliver of his humanity remained due to the Sin of Solace, who preserved it to torment his host better. 

And so, the vile madman came to regret pursuing his wish. He schemed and conspired to bring Nephis back to life and create such a cycle of the Great River where the Nightmare could be conquered by the cohort. He turned his friends into the Plagues, and then betrayed them, arranging for each to be slaughtered. 

But was that all that the Mad Prince had wanted?
