They were very similar to Special Weapons Dalek, however, their cannons utilised temporal radiation mined from the Tantalus Eye. It would flow into their targets' bodies through available orifices before erasing them from history. The results of these targets' actions would remain, and memories of them would not be wholly erased. They were also durable enough to withstand fire from a Dalek gunstick, although it could still damage them.
The Eternity Circle planned to create a new paradigm of these Daleks and spread them throughout the universe through the use of the Daleks' progenitors. However, the new paradigm was never deployed because it and the Eternity Circle were erased from history by the War Doctor and Borusa. (PROSE: Engines of War)
