I think this page from Well of Daliath may illuminate part of this discussion around how Kallyr is read. I haven't been a huge fan of how she's been presented in the text myself.

Oh, Argrath was dead in a ditch during the short RQG game I ran. I am the person who would only run Star Wars, using a New Hope as canon and would start with an event that kills off all the major characters (good and evil).
In my upcoming Legendary Duck Tower game, I'm having a npc named Arquack, who is going to play a Zote (from Hollow Knight) type role as a special encounter.
I think he (Argrath) is kinda a boring authoritarian. I haven't liked how the important npcs are presented. Not for any canon reasons, but they lack the style, substance and utility I look for in gaming material.
