They were:
"Be gone."
And as he said them, the world shuddered.
The wraith's eyes widened slightly — this time, in earnest.
"You…"
And then, he was gone.
Erased, as if he had never existed.
The splintered part of Sunny's mind was gone, taking the forbidden knowledge of the Void, and all the memories of the previous cycles, with it.
Preventing the Mad Prince from ever being born again.
Healed from the curse that had plagued him since the early days of the Southern Campaign, Sunny closed his eyes for a moment, and then let out a long sigh.
Then, he looked down.
There was a thin thread tied around his neck — the same thread with which the mouths of the Voiceless Prelates, a band of Corrupted Demons led by a Devil named the Defiled Herald, had been sewn shut. Sunny had slain them back in Antarctica, receiving a certain Memory in the process.
That Memory was the Stifled Scream, a charm he usually used to augment Saint.
The charm possessed a second enchantment, though, which the graceful knight had never been able to use.
[Word of Power] Enchantment Description: "A word spoken by the master of this charm is a command. If born of great silence, the word of power can hardly be ignored. If not, it has no worth."
Saint never spoke, so [Word of Power] could not be used by her. Sunny, meanwhile, was never able to remain silent for long enough to let the enchantment accumulate enough potency.
The longer one remained silent, the more tyrannical the authority of the [Word of Power] would become.
And so, knowing that he might face the machinations of the Mad Prince in one way or another, Sunny had summoned the Stifled Scream.
That was the Memory he had summoned while bidding farewell to Cassie.
And ever since then, he had not made a sound.
The Great River was a river of time. And so, by traversing it, Sunny had let the Stifled Scream accumulate a lot of power… but much more than that, he entered the Estuary while wearing it.
Time did not exist in the Estuary, which meant that there was no difference between a single moment and an eternity here.
How dreadful would a silence that had lasted for an eternity be?
…Dreadful enough to obliterate the Sin of Solace, it seemed.
And powerful enough to save Sunny's life.
Not having to maintain silence anymore, he took a deep breath, and then cursed quietly.
'Damnation. You go to hell... me.'
The Mad Prince was gone.
This time, forever.
Which meant that Sunny had joined the exclusive club that Jet, Kai, and Cassie were already members of. He had vanquished an evil version of himself.
It also meant that the path to the heart of the Estuary was completely free.
Picking up the Guiding Light, Sunny dismissed Saint and headed for the vague shape rising above the dark waters of the nebulous lake.
The final secret of the Tomb of Ariel awaited there.
