Alternatively, teleport to Canifis, then go via the Myreque shortcut to Burgh de Rott, or use the Minigame Group Finder and its teleport option for Shades of Mort'ton (activity). There is an Agility shortcut between the town of Burgh de Rott and the Haunted Mine area. Climb over the mine cart just south of the Zealot (featured in the Haunted Mine quest), and enter the haunted mine, then travel north and enter the lair. Upon entering the room, a cutscene will appear showing Mutant Tarn and two terror dogs.
