I was thinking that maybe we were both part of that travelling group all those years ago, Yttermayn. When the camp was attacked, you escaped into the shadows because you blend so well, assuming mistakenly that everyone else was dead. I think what happened between then and when we were reunited is up to you, but I think it should have been immediately after Hraln exacted vengeance upon the traitor. Your character had a vision that they needed to be somewhere at a certain time, and that was right where Hraln turned out to be the day after his quest came to an end.
Perhaps when they first saw each other they almost came to blows, thinking each other were also traitors, but they realized through whatever means (like detect alignment) that this was not the case, and that both were true. Obviously it seems mysterious that they are re-united exactly after Hraln had defeated the traitor, and not before, but they can accept that it was part of the nature of their callings. Your character was not meant so much for weeding among the faithful as people like Hraln.
How does that sound to you? Any modifications you would like to make?
