'Now, let's sort everything I have heard so far.'
So basically, Liora wasn't from Earth, that was why she didn't recognize the food I made.
In the novel she read, Arthur got corrupted after many different events, causing him to become an evil Origin which was obviously the Origin of Order.
The hero and the one who tried to stop him was Adrian, who apparently was the demon king in my version of the novel, but in Liora's version, he was only a knull prince who wanted to unite the world.
According to her, she died only one hour after reading the ending, and ended up in this new body.
"And you are telling me, you were killed by Zephyr at the banquet?" I asked Liora, and she gave me a nod.
"The owner of this body had a hidden identity. Her mission was to simply kill Zephyr. Obviously, she was the one who died."
So I really wasn't the one who solved the banquet's incident, but her. She was one of the attackers, and to survive, she betrayed the knulls.
