Cardinal completes her story, in which Quinella, basically running out of soul disk space, copies her memories to a young girl’s fluctlight, overwriting whatever was there. But Cardinal, now possessing a good deal of Quinella’s powers, decided to try to make her move. She fails, but was able to flee to the Great Library to fight another day.
Their duel is brief but exciting, despite all the awkwardly long English incantations the two must make (“System Call: Generate Luminous Object”, etc.) For 200 years since being banished to the library, Cardinal has been observing the Underworld, waiting for the right person with which to collaborate. She used a little spider named Charlotte to help bring Kirito to her.
Cardinal also suspects the god of the outside world (i.e. Rath) aren’t doing anything about Admin because the happiness of the people of the Underworld isn’t their primary goal. Rather, the whole system is a load test to see how much they can tighten the vise on a civilization before it loses cohesion.
Cardinal also tells Kirito that this isn’t just about defeating Asmin and ending her domination over the Underworld. The Forces of Darkness beyond the Realm of Humanity are planning a massive invasion, and Admin’s Integrity Knights are far too few in number to repel them, and she had all four guardian dragons slewn because she couldn’t control them, further hampering her defense.
Cardinal isn’t going to allow the Forces of Darkness to invade the Realm of Humanity; she’s willing to destroy the Underworld and start over to keep that from happening, and this is why she needs Kirito and Eugeo’s help.
If they successfully defeat Admin and Cardinal regains her authority, she’ll let Kirito save “about ten or so” Fluctlights, which if I’m honest, is close to all of the people in the Underworld who mean a lot to him (Cardinal also asks, and is given, a simple human hug, which she considers more than adequate reward for her efforts).
Of course, that’s not ideal, and Kirito will be searching for a way to have their cake and eat it too (I mean, he wouldn’t be Kirito if he didn’t). As for saving Alice, it turns out to be just a simple matter of ejecting the “piety module” from her head that’s blocking her past self, by reminding her of her most treasured memory—stored in Admin’s chambers.
Kirito and Eugeo’s mission has similarly simple steps, though of course they’re all easier said than done: First grab their newly-improved weapons from the third floor. Then, go to the 100th floor to recover Alice’s stored memories.
I have no doubt the 97 floors in between will prove a challenge, but should they run into Alice herself, Eugeo is given a dagger that will connect her to Cardinal, who will put her to sleep. So that’s the plan…all that’s left is to execute.
