There are four Immortal Lords aside from Rory inside the garden; however, only one of them caught Klaus's attention.
He, of course, is Star Lord Victor, the overlord of the Astryx star system and the king of the Stella human race.
It wasn't that the others are insignificant. They are important and extremely powerful; however, Klaus is the kind who has a sixth sense for danger, and as such, he saw Star-Lord Victor as a danger to his life.
Klaus, for the first time since he had started his journey as a warrior in this life, laid eyes on someone he saw no openings in their defence, not even a small flaw that he could exploit.
Because of his past life experiences, whenever he laid eyes on someone, his first instinct was to look for openings, just in case they suddenly attacked him.
Many warriors do that, so in a way, it is normal.
