duhwro: The quest is :"To be named the commander of the brotherhood of the rightteous, I have to demonstrate my abilities by bringing back the monstrance of Saint Orthenius ,apprehending the culprit who stole it from the hillbrandt's church some time ago ,and killing a given number of enemies of God and king..."

I found the Monstrance and gave it to someone in the church,and I have killed a large number of monsters,so I guess the missing part is the culprit who stole it?I have no clue about it. Could someone tell me how to get this quest solved please?

Feidlimid: Have you tried talking to the priest that is outside of the church, a little bit to the west ? ( Don't forget to search in the forum if your question hasn't already been asked ;) )
