She was the Overseer of the Floor Guardians of the Great Underground Tomb of Nazarick, Albedo. She was in charge of the seven NPC Floor Guardians. In other words, she was the highest-ranked character in the Great Underground Tomb of Nazarick.
Because of that, she was permitted to await orders within the Throne Room, in the deepest reaches of the Tomb.
However, Momonga turned a sharp look on Albedo:
"I knew there was a World Class Item here, but how is it that there are two of them here now?"
In YGGDRASIL, there were two hundred ultimate items in the game, known as World Class Items.
World Class Items possessed unique abilities, and some of them were so balance-breaking that they could even request changes to the game's rules by the developers. Of course, not every World Class Item possessed such insane power.
Even so, a player who possessed even a single World Class Item would be catapulted to the highest echelons of fame in YGGDRASIL.
Ainz Ooal Gown possessed eleven items of them, the most of any guild. Even that was far in excess of any other guild. The guild in second place only possessed three such items.
With the permission of the other guild members, Momonga was allowed to possess one of these ultimate items, and the rest of these World Class Items were scattered throughout Nazarick. However, most of them were stored in the depths of the Treasury, defended by its Avataras.
The only reason why Albedo could possess such a rare treasure like this without Momonga's knowledge was because the guild member who designed Albedo had given it to her.
However, since today was already the last day of the game, Momonga felt that he should respect the wishes of his comrade who had given the item to Albedo, and so he did not take further action.
"This is a good place."
Momonga's words were directed to Sebas and the Pleiades as they reached the base of the stairs leading to the throne.
After that, he began climbing the stairs, but stopped when he heard footsteps behind him. Momonga could not help but laugh, although his skeletal face could not show any expressions.
The NPCs were merely inflexible AI routines. If he did not give a specifically-worded command, they would not recognize it as an order. Momonga had forgotten this and thus he had not properly commanded the NPCs.
After his guild members left, Momonga had begun solo hunting by himself to a nearly ridiculous degree in order to earn the gold needed to maintain Nazarick. He did not build friendships with other players and avoided them, as well as the high-difficulty areas he used to visit when his guild members had still been around.
Then, he would deposit his earnings in the Treasury before logging out. This had been his routine for almost every day. As such, he did not have much contact with the NPCs.
"—Stand by."
The sound of footsteps stopped.
After Momonga gave the correct command, he ascended the final steps and arrived at the throne.
He stared openly at Albedo, who stood by its side. Though he had entered this room before, he did not recall her eyes tracking him in his memories.
"What kind of backstory was she designed with?"
All Momonga knew about her character was that she was the Overseer of the Guardians, as well as the highest-ranked NPC in Nazarick.
Driven by curiosity, Momonga opened up a console and began scrolling through the details of Albedo's flavor text.
