The 12th Seat in particular accompanied three other of his teammates in negotiating with the Kingdom's two adamantite adventurer teams; Blue Roses and Red Drop's leader Azuth Aindra to join the Slane Theocracy. He kept his presence hidden for a very brief period of time during the meeting between fellow members of Black Scripture and adventurers of Blue Roses and Red Drop while they were discussing. The adventurers did not in anyways notice his presence among them until he decided to reveal himself openly much to their surprise. Feeling caught off-guarded by the sudden appearance of another member of Black Scripture who was listening into their conversation, it made Tia and Tina realize that he is a better and stronger assassin than the both of them.

After the adventurers refused the Theocracy's offer to escape to their nation, he nearly lost his composure when Azuth mentioned Rufus, but was restrained by one of his companions and told to peacefully leave the inn.
