Andar was becoming excited, but the words from the other head quieted his enthusiasm, "Note little apprentice, each Engraving Slot for the Endless Vault is harder than those of the Revolving Core, for every single Engraving Slot you unlock is as difficult as unlocking ten Engraving Slots for the Revolving Core Art, and for everyone who had ever practiced this Meditation Art, the highest never went beyond the 92nd Engraving Slot."
"This level is very important, because a Meditation Art would only give you a Divine Ability when you unlock its 100th Engraving Slot, so any Meditation Art that has less than a hundred Engraving Slots would never have any chance of having a Divine Ability."
"Does it mean that no one else knows of the Divine Ability of the Endless Vault?" Andar asked.
"Who knows." The Steward responded, "Even if no one has reached that level, it would be incorrect to assume that greater powers may not have deduced the power of the Endless Vault."
