Our journey, for those of you who wish to re-create it for your own amusement, started in the Undercity. From there we went through Western Plaguelands and into Eastern Plaguelands to pick up the first flame. (Most of us travelled on to pick up the flight path at Light's Hope Chapel.) Then we went back through Western Plaguelands and cut down to the Hinterlands (yes, there's a path near the bridge to Scholomance that sends you out right near Aerie Peak.) After picking up the Hinterlands flame, we continued on to the Horde flight path at Revantusk Village and then jumped into the water and swam south, down to the Wetlands. From there we ran through Loch Modan (meeting a friendly Gnome near the Thelsamar graveyard), through the Badlands (picking up the flight path at Kargath), and into Searing Gorge for the third flame. From here, we ran through Blackrock Mountain, into Redridge, through Duskwood, Deadwind Pass, and Swamp of Sorrows, finally winding up in the Blasted Lands for the forth flame. Finally, success!
