I just wanted to post this, as I couldn't find the information elsewhere. I completed this turn in with "warmly" faction to everyone inside Thurgadin and I was "kindly" to the guards outside. I read elsewhere that if the turn-in NPC will tell you what items you need for a specific piece, then you can do the turn-in, not sure if this is true, but you do not need kindly or ally faction. I did cast collaboration on the NPC and was still warmly, fyi
