History
The Dimension Smasher was a device created by Enoch Mason that allowed contact between Earth and Smokeworld. It was used by Vision to travel between the dimensions.[1] With the rift open, the device was the only thing keeping the beings of Smokeworld from passing into the Earthly plane, that was until a mobster infiltrated the Enoch family home and a stray bullet opened the rift, allowing a Kalimachh to pass through and go on a rampage. While Vision dealt with the creature, Enoch reconfigured the device to permanently close the rift.[2]
