"Saint Cassia must have informed you that my shop is actually an Ascended Devil. In fact, the volume of its interior... seems a bit too vast, doesn't it?"
She lingered for a bit, then shrugged.
"It is hard to say without knowing what creature you killed to receive this Echo. But yes, I would have expected it to be much smaller. Dimensional storage Memories of the Ascended Rank are usually much more modest."
Sunny pointed at himself.
"But, you see, this dimensional storage is a bit unique. Because its volume does not depend on the creature's Rank and Class, but rather on the potency of the creature's master's soul. Which, in this case, would be my soul."
Nephis remained silent for a moment.
"It seems that you have an unusually potent soul, then."
He chuckled, causing a small smile to appear on her lips.
"Thank you for the compliment. That is not the point, though."
She frowned, then suddenly pierced him with an
intense gaze.
"Do you mean to say..."
Sunny nodded.
"Indeed. It is not impossible for me to create a Memory that is bound to its wielder's soul, and is thus as powerful as the wielder is. You strike me as someone who will continue to grow stronger, Lady Nephis. So, it is not impossible for your sword to become sharp enough to slay a god, one day."
Sunny was being a little dishonest... but only a little.
In truth, his ambition was not to replicate the enchantments of the Covetous Coffer. What he was after, and had been trying to achieve for a while now, was to replicate the [Bound] trait of the Onyx Mantle, which was responsible for that Attribute of his being as potent as his soul was.
The reason for that was the shift in his perception of power, and his views of Memories, after becoming Transcendent. Sunny had long realized that truly powerful beings did not pursue greater power from the weapons they wielded and the tools they used - because they themselves were the power. The weapons and the tools were only meant to channel their own strength, not be a source of external might.
And yet, it had always been the opposite for Sunny. He had made himself into a lethal warrior, yes, but most of his victories came from cleverly using the enchantments of his powerful Memories, which he could utilize better than other Awakened due to his eyes having been altered by Blood Weave.
Being banished from the Spell, he had lost most of these Memories. That had shown him, in a rather cruel manner, the difference between internal and external power.
So, even though Sunny could craft himself a diverse arsenal of potent Memories, he had not done so. Because he was powerful enough to not need it, and did not wish to be led astray by excessive reliance on undeserved strength. He would rather achieve such strength himself.
That way, he would be following in the footsteps of those who were truly divine.
So, the only Memories Sunny wanted to craft for himself were those that would help him channel his own power better, or provide simple convenience. He also wanted these Memories to be able to keep up with his progress.
Therefore... he had to master the [Bound] enchantment.
The problem was that forging a Memory that possessed such a trait was not easy, since it had to be intricately tied to one's very soul.
...But it would be different if Nephis and her soul flame, as well as the Crown of Dawn, were there to help him.
