Orion saw a man walk in the hall, followed by the members of the Silverflame Family. The man appeared to be around 19-20 years old and was one of the Silverflame Family's geniuses.
But that didn't make Orion change his expression; it was the mask that he wore on top of his face.
It was a white mask like he had but his appeared rather skintight, usually used for changing appearances and it was a magical treasure from what he could see.
Because the mask was a treasure and needed mana to change appearances, Orion could only see the white mask instead of the appearance the white mask had transformed into.
Unlike him, all the humans present here could see that the man with the mask in the Silverflame Family was just any other man. They were unable to see the mask because it had transformed into the skin of another human.
As a result, all they saw was another human.
