Sunny's theory that mastering the remaining steps of Shadow Dance would allow him to shadow the Attributes and Aspects of other people, as well as profane powers of Nightmare Creatures, was not built entirely on pure conjecture.
Sure, his intuition was telling him he was right, but sadly, his intuition was not what it used to be now that Sunny was cut off from fate.
However, there was also something that corroborated his theory. A piece of information that Sunny had noted a long time ago, but never managed to explain before now.
It was the scope of powers that the Mad Prince had seemed to possess.
The Mad Prince, Sunny's own past self, had been a Corrupted Titan. He had attained Transcendence — or rather, descended into the abyss of Corruption — all on his own. He had also formed the Titan Core in the depths of the Tomb of Ariel, somehow, despite the dire number of shadow fragments that would have required.
