Clue I

"It really is the Neverending Book… You're lucky to obtain the Neverending Book and bring it here to me. If it was anyone else, they would have no way to decipher the runes of the Neverending Book. However, the great Sir Didimoss is able to do it!"

The magnificent black cat's voice became sharper. Following that, Merlin sensed that the stone tablet which stood on the beach was beginning to shake softly, after which mysterious runes appeared one by one and were slowly grasped by the black cat.

At the same time, Merlin perceived that streaks of powerful Mind fluctuations had emerged around the black cat. This gust of Mind Power made Merlin scared out of his wits.

Mind Power was something intangible. In reality, it was unable to cause any physical injury to anyone. However now, Merlin could feel the waves of Mind fluctuation around the black cat Didimoss as if once Didimoss' petrifying Mind Power was targeted at him, he would have no resistance at all.
