Dimensioneer

The Dimensioneers were a faction of Time Lord pioneers that sought to cross the dimensional divide and bestrode the infinity of dimensions. They created interdimensional corridors with which to cross the space between dimensions. They also created the dimensional nodes, which the Master considered made the Key to Time look like a trinket. The two nodes, when linked to the node activator, required a Time Lord to be slaved to them, and could access interdimensional energy. They were eventually banished by the Time Lords, and their technology locked away as they fell into legend. (AUDIO: UNIT: Dominion)
