Kenon isn’t a who, it’s a what. It’s a concept elaborated on by Linos that can become a basis for the third religious option.
Suzane is the female Simon. She’s a noble who’ll join you if you aren’t too anarchic, and has COM 3 (this can be inferred from hidden information in the code).
Korszata and Bjel are Whendish renegade Phalangites who will join you if your Cosmopolitan is very high. They are both very effective commanders of spearmen, though they are not quite as skilled in personal combat as Simon/Suzane.
