The Abandoned Mole Machines are a system of traveling within Blackrock Depths added with Cataclysm. There are three abandoned machines, which can take you to three different locations (basically the other two locations from each location). * The 1st machine is at the entrance room of Blackrock Depths. * The 2nd on rounded terrace behind locked doors outside the Grim Guzzler. * The 3rd machine can be found at in a nook in the Domicile.
