Astro looked at the master only to see that his eyes were closed and he did not voice out any disagreement so he deemed that it was okay to tell the major who Ari was. It was also better so that when those whatever state ever happened again, Ari can share the information to both of them.
"Ari is someone that the master tasked to gather information for him." He pointed to the side and slowly a woman started to appear.
Linius thought that nothing right now would be able to surprise him but this one was out of his expectation. Ari was like a ghost and when the man tried to touch her, his hands passed through her and yet she has no reaction.
"This is Ari. She is helping with gathering information about the tower because she could store several pieces of information inside of her," the mage explained. "She could also spy on the enemies if needed because she appears invisible even without magic."
