We met Murral just before we got to Neverwinter he found us while we were camping and wanted to come in with us once we got to Neverwinter. Once we got to Neverwinter he disappeared and we found out that he had taken some of our weapons and rations. Went to find him at the Neverwinter Thieves Guild where we met Ruald Knell. Turns out he was using Murral to bring us there in the first place.
