I'm not sure exactly how to implement those. Give recommendations and I'd be happy to.
I could expand on the PoR section by mentioning Naesala's piracy and Kurthnaga being a witness to the scene, stuff like that.
But he didn't have interaction with Rajaion, Ena or Nasir in PoR, and that's what I'm focusing on. Since they didn't interact with him in PoR I felt it was unnecessary to mention them.
