And that was it.
There seemed to be only one enchantment, but it had no name and no description. It was just like the [Where is my eye?] enchantment of Weaver's Mask, which had not been named until Sunny used it.
There was one difference, though... [Where is my eye?] was an active enchantment, while the enchantment of the Estuary Key seemed to be a passive one.
Sunny took a deep breath.
'So... what is the probability that Soul Serpent had killed a Great Terror while I slept, and that the Memory received by me as a result has to do with the Great River?'
That was the only logical explanation, and yet, the logic of that explanation was highly questionable.
He remained motionless for a while, then sighed and summoned the Key of the Estuary.
Of course, it would have been more prudent to first study the mysterious Memory in the Soul Sea... yet, somehow, Sunny felt reluctant to touch it within his soul.
Soon, countless sparks of darkness swarmed around his palm, and then slowly formed into a jagged piece of black stone.
The jagged stone was utterly black and cool to the touch, reminding Sunny of the building blocks of the Tomb of Ariel. There were no features to it, no runes or images carved into its surface. It was just a rough, palm-sized chunk of stone that seemed like something one would randomly pick up from the ground.
Since the mysterious enchantment of the Estuary Key was a passive one, it was supposed to come into effect as soon as the Memory was summoned. However, if it was doing something, Sunny couldn't tell.
He did not feel any changes, neither in himself nor in the world.
'Ah... I feel like I'm going mad.'
He had been bombarded by more and more bizarre questions since the start of the Nightmare, and none of them had any answers.
There was also an answer that didn't seem to have a question.
Even the Sin of Solace had become a bit weird.
Uttering a quiet curse, Sunny concentrated and peered beneath the surface of the jagged black stone.
Even if the enchantment had no name and no description, he could still study its weave himself. After all, by now, he had some knowledge of weaving, as well as the ability to intuitively feel the purpose of various weaves.
Within the Estuary Key, there was a vast tapestry of ethereal strings. It was not the most complicated spellweave Sunny had ever seen - that would be the weave of Weaver's Mask - but it was still incredibly complex, and unimaginably intricate. An enchantment like that was hopelessly outside the scope of what he himself could create, at least.
Sunny was stunned.
However, he was not stunned by the intricacy or complexity.
Instead, what paralyzed him were the strings themselves.
Because, unlike the strings of soul essence that comprised the weaves of all Memories created by the Spell, these ones were not ethereally luminous and silvery white.
Instead, they were lightless and dark.
...Like something Sunny himself would create.
