This Ornton guard displayed kindness through his sympathy for Chelsette, or rather, for the courtesan who she impersonated. Due to how easily he fell for this ruse, he may have been somewhat oblivious to reality. However, because of how late it was, he may have simply been unable to think clearly, making him an incompetent guard. Either way, he did fail in his duties by inviting Chelsette into the library.
In the year 212, this Ornton Guard was, at least for some period of time, stationed in the hall leading to Count Orelius' palace's library.
