Schematics for it could be found in Scarlet's Secret Lair. Before it finished construction, it was used to control the Twisted Marionette. After one of Scarlet's Energy Probes identified an intersection of magical ley lines beneath the ruins of Old Lion's Arch, the drill descended into the city, where it began burrowing deep into the earth under the protection of Scarlet's Alliance.
Engineers who found their way into the airship noted from its design that its purpose was never to tap into the power of the ley lines, but to disrupt them. Shortly after Scarlet's End, the Breachmaker fulfilled its purpose, striking the mass ley line intersection underneath Lion's Arch and sending a surge of power along the ley line that runs past the Thaumanova Reactor. This appears to have captured the attention of the sleeping Elder Dragon Mordremoth, as it roared when the ley lines were struck.
The drill continued running for a few days until the airship mysteriously exploded. It is said that the surge of power along with Scarlet herself causing the core of airship to become unstable were the reasons behind the explosion.
Nowadays, part of the drill can be found at the Wreckage of the Breachmaker.
