Upon traversing the world of Lord of Mysteries, Arthur awakens a unique "Logic" pathway.

【Sequence 4: Director】—The world is my stage, and cause and effect are my script.

【Sequence 3: The Logic Mentor】—Definition is truth, paradox is miracle.

【Sequence 2: The First Paradox】—I am the exception to the rules, I am the blind spot of order.

【Sequence 1: Mentor of Civilization】—I am civilization, I am law.

When he stood shoulder to shoulder with Klein atop the Source Castle, facing Amon's deception and the invasion of the Outer Gods, Arthur smiled calmly:

"Since logic can't solve the problem, let's create a 'paradox'."

Rigorous and extraordinary deduction, extreme logical reversal, an ultimate war over the "right to define".
