i just copied this response from reddit since it pretty much sums up who kuahel leon is (my memory is also jumbled since i read the novel months ago already)
reddit response (with some additions from me):
in book 2, the holy knight is in charge of the expedition to investigate if the ancient warlocks (a long time ago, 1/2 wizards went to the tower, 1/2 fought and were exiled) were the brains behind the big monster subjugation in book 1. he's loyal to the church, whos keeping the secret that an important stone was stolen during the war, so he and the other holy knights spend the whole book trying to recover the item while keeping tabs on the tower wizards to make sure they don't get their hands on the same type of black magic. hes a good character in the sense that he ends up often saving maxi's life/helping maxi, she trusts him and he somehow subtly and maybe subconsciously cares for maxi, which makes riftan jealous xD his main thing as a character is someone very likely with anti-social personality disorder who’s found structure and control for his violent tendencies in strict religious and military life.
sources if you wanna read more insights on him, his character/role in the book, and relationship with maxi and riftan:
