This guy is at loc -1088.44, -1422.68, 5.62 in the SE corner of zone. If you don't have high enough faction to buy from him, just do the tonic turn in quest in Erudin (buy vasty ale from the guy in the Bluehawk, which is the first building to your right when you get to Erudin). Zone into the Palace and go down to where the bank is. Go into the City Office to the left of the bank and go into the door to your left...following those doors until you hit a jail-like door and follow that downstairs until you get to the jail area. The turn-in gnome will be in the jail cell to your right. Just hail him and say "what tonic". You can turn in four at a time. This will increase your merchants of Ak'Anon quickly (depends on what your faction is now). A cheap and quick way to merchant faction. ;-) This is the quest in case you need to actually see it: https://everquest.allakhazam.com/db/quest.html?quest=3548
