The Walahra Turban NPC's friend has been missing for like, 2 weeks. He came back tonight and I finally had some spare gil and IS to get the 20 Imperial Gold pieces required for the quest. I took a trip to Nashmau and as I started converting them a level 8 mamool Besieged came and leveled Al Zahbi. NPC was taken again. Inventory -11, fuck you, SE.
